So we are going to look at some regular nouns and some irregular nouns. So let's get started! So, we're going to start with the easy ones. So let's look at the regular nouns and the basic rule is that we simply add an "s" to the end of the noun to make it plural. So for example, house in the singular is houses in the plural. So you can see here, we simply add an "s" to the end of house. And some other examples... coat, coats dog, dogs ship, ships okay.. road, roads and... many more examples. So this is the basic rule. This is probably ... the majority of nouns in English are just regular nouns and they follow this rule where we simply add an "s" to the end okay. Now since this lesson is a grammar lesson and not a vocabulary lesson, then I won't be defining these words okay? So if you don't know what these words mean, then I suggest that you look in a dictionary okay? That is not the aim of the lesson today. The aim is to teach you the grammar rules not to teach you the vocabulary alright? So the first exception to the rule. So the first type of irregular noun is the group of nouns which end in "ch", "sh", "s" (or an "s" sound), "x" or "z". So for all of those nouns, in the plural, we form the plural by adding "es" to the end. So example: church, churches. dish, dishes. bus, buses. box, boxes. buzz, buzzes and many more. So these are... these all have the same rule. So we simply take the singular form and in the plural, we add "es". So there is an extra syllable when we pronounce it. So you should be able to hear it. In the singular, there is one syllable "church" and in the plural, it's "church -es" So 2 syllables: churches, dishes, buses, boxes, buzzes. So it is important that we hear the extra syllable when you pronounce it. So, now nouns which end in the letter "y". First of all, if the noun ends in first of all in a consonant and then the letter "y", then, in that case, we change the "y" to an "i" and then we add "es" to the end. So an example: lady, ladies. So you can see here, in the singular, the end of it has a consonant. So the letter "d" is a consonant, followed by the letter "y" and so we follow the rule: We change this "y" to an "i" and then we add "es". So city, cities. baby, babies. ferry, ferries and... there are many more... ok? Now, there is another case here, there is another example of... we can also have nouns that end in a vowel and then the letter "y" And here this is just like a regular noun. So we add a letter "s" to the end. So a reminder: a vowel is the letter a, e, i, o or u ok? So boy, boys day, days key, keys OK? And again, there are many many more. So this is not... these are not the only ones. This is just a very small sample. There are many more examples here. So the rule when the noun ends in "y" - If it is a consonant and then the letter "y", then we must add... we must change the "y" to "i" and add "es" and for all the other cases when it ends in a vowel first, then we just add the letter "s". Ok... and this time we are going to look at nouns which end in a letter "f" or "fe" at the end. Ok... so there are a list of nouns now that I am going to give you which you must learn because these are irregular. So the nouns which you're going to see now... the rule is that we change... we replace the letter "f" or if it is "fe", we replace that with "ves". Example: leaf, leaves shelf, shelves And listen to the pronunciation ok? The pronunciation - we... we must hear the letter "v" in the plural. life, lives wife, wives calf, calves elf, elves half, halves knife, knives loaf, loaves self, selves thief, thieves wolf, wolves Alright, so in all of these examples that you can see here, this... they follow this rule. So we changed the "f" to... "ves" Or if it ends in "fe" like here... "knife" then the "fe" changes to "ves" and we say knives. So... these are the exceptions, and for most of the other nouns, okay, so pretty much the rest of the nouns which end in "f" or "fe" then they are just regular nouns... and we just add "s" to the end. So just two examples: roof, roofs and giraffe, giraffes and many more ok? So my advice for you, for nouns ending in "f" or "fe", my advice is for you to learn this list here at the top. These are the most common examples of nouns where you have to change the "f" (or "fe") into "ves" okay? So if you learn this list at the top, then you know all the other nouns are just regular okay? So this list at the top is the exceptions okay? These are the ones where you have to change it to "ves" and all the others, or most of the others we just add an "s" ... okay? Let's carry on. Now, nouns ending in the letter "o" This is a little bit more complicated. So we'll start with the easy part first. So the easy part is the nouns which end in a vowel and then the letter "o" So, those are the vowels.. and this is easy. We just add the letter "s" to the end. So we ... we treat them like a regular noun. So just a couple of examples here. There aren't many examples of this so we have radio and this becomes radios in the plural. So we just add an "s". So we can see here - The end of the noun has a vowel. The vowel is the letter "i" followed by the letter "o"... and so we follow this rule. We add a letter "s". So radio is radios and zoo is zoos in the plural So again, the letter "o" is a vowel followed by an "o" and so we just add a letter "s" There are a few other examples of this but there aren't very many to be honest with you. The important one is nouns ending in the letter "o" with a consonant. So a consonant plus the letter "o" We have, first of all, we have some irregular nouns... and for the list that you're going to see we add "es" to the end. So you must remember this list okay? You must learn this list of nouns. So potato, potatoes So the pronunciation is the same. There is no difference in their pronunciation. It is the same pronunciation as if there was just an "s" at the end. tomato, tomatoes hero, heroes echo, echoes veto, sorry veto, vetoes or veto / veto. Yes it's pronounced veto in fact and vetoes. torpedo, torpedoes embargo, embargoes buffalo, buffaloes domino, dominoes. mosquito, mosquitoes. Alright, so just before we carry on, so all of these nouns on the left, again you must learn this list okay? These are the exceptions. These are the irregular nouns which end in the letter "o". So for all the others, okay.. so for all the other nouns - Some of them... some of the others... we must just add a letter "s". So some up the others... they are just regular. We just add a letter "s" ... and some of the others, we can choose to either add a letter "s" OR "es" okay? So both would be correct. Either would be correct. So since both would be correct, then to make it easy for us, then we are just going to add an "s" for all the others because that makes it more easy ok? So for example: casino, casinos. photo, photos. solo, solos. volcano, volcanos. tornado, tornados and many more ok? So again, just to summarise, learn this list on the left okay... so that you know these nouns here, in this list, in the plural, you have to add "es" and in all the other cases... in all the other nouns, then just add the latter "s" ok? That makes it easy for you. Just add a letter "s". And in fact these words here, this list will always stay the same because these are quite old words in the English language. All new nouns, all new words which end in "o" in the English language, they follow this rule on the right. So we will always add "s" to new nouns which end in "o". So all you need to do is just to learn this list and any other nouns, just add an "s" to. Now in the English language, there are sometimes... we have a few words which come from Latin and in fact Greek as well. So we have to... they have a slightly different rule in the plural. So there are some Latin nouns which end in "us" and for those nouns, the plural... it is a Latin plural. And the Latin plural, we add a letter "i" So we change the "us" to "i" And there are a few examples here: So nucleus, is nuclei cactus, cacti fungus, fungi radius, radii stimulus, stimuli Whoops! So you can see there again, we change the "us", and we change it to "i" There are maybe... maybe a few other examples but these are probably the most common ok? So just a reminder - These are English words but they have a Latin origin to them. So we use the Latin rules to make the plural. And we also have another group of foreign words which end in "is" in the singular. And for those words, the plural, we change the "is" to "es". So example: axis, becomes axes. So we pronounce it EES at the end. axis, axes. analysis sorry! analysis, becomes analyses. crisis, crises diagnosis, diagnoses hypothesis, hypotheses thesis, theses Again, these are... these are NOT very common words. So do not panic! Do not worry too much about these but it is important that you you know thats these words, in the singular, when it is "is", that they become "es". It's.. it is useful if you see these words written, that you know for example, if you see the word... analyses ("es"), that you know it has come from the word analysis ("is") in the singular. And all of these are Greek except the top one. This axis is Latin and all the others are ... Greek in fact. They have a Greek origin to them. And finally for the foreign nouns, we have some nouns which in the singular end in "ix" or "ex"... and in those cases, we change the "ix" or the "ex" and we replace it with "ices". So for example: appendix, appendices. So you can see here the "ix" here. We have removed that and we have replaced it with "ices". Listen to the pronunciation matrix, matrices So "ices" We pronounce it "ices" matrices index, indices vertex, vertices So again, do not worry! These are not very common words. Well, perhaps index - that is probably the most common. And again these are Latin words. They are from the Latin language and so we follow the Latin grammar rules in the plural for these words. There are perhaps a few other examples as well, but these four are the most common. There are maybe another four or five examples in the English language... but nothing too important okay? And irregular nouns. So there are some nouns in English which do not follow any rules at all... and you simply just have to learn these nouns. They are completely irregular. So foot, feet. child, children man, men woman, women. goose, geese. mouse, mice. person, people. tooth, teeth. ox, oxen Again, there is nothing really that I can explain here. There is no logic or rules here. You simply have to learn this list ok? So again, look in the dictionary if you want to know the meaning of these words. And a lot of these words... these words are actually very common.... ok... apart from... ox is an animal and it's not very common but the rest are very common words in fact. So this list is important. Okay I recommend that you learn this list. And... finally there are some nouns in English which are exactly the same in the singular and the plural. Okay it's quite a unique situation but there are a few. So: aircraft. We can say one aircraft or three aircraft. it's the same. spacecraft one spacecraft, three spacecraft. hovercraft, hovercraft. So you can see here, any word which ends in craft, craft, craft. It is the same in the singular and the plural. sheep, sheep. So one sheep or three sheep. It's the same. fish, fish. So you never say fishes for example, and you never say sheeps. "Sheeps" - that would be wrong ok? one sheep, two sheep. One fish, two fish. deer, deer. So these are all animals. We've got sheep, fish, deer. moose, moose. Okay so... I'll just go back very quickly... so again there are a few others here that exist as well but these are the most common. These are the most common nouns which are the same in the singular and the plural. So that is the end of the lesson. There, in the lesson, we have seen probably ninety percent of all the rules for how we form the plural for nouns okay? So we have seen ninety percent of the most common examples... and the other 10 percent aren't very important so ... if I had to explain all of them, then the lesson would take hours and hours and hours! But that is most of the examples. So there we are. That is the end of the lesson I hope you have enjoyed it.
