hello grammarians today we're going to be talking about the irregular plural previously I had said that if you take any English word any noun say the word dog and you tack an S on to the end of it like so Boop you get the word dogs and that's how you form the plural in all cases I was lying sorry it turns out that English uses a little bit more complicated than that while adding an S to things is the way you usually make things plural sometimes there are other changes and sometimes you don't even PluralEyes using an S at the end but we're not going to talk about that now that's for another time what I want to talk about today is the most basic kind of irregular plural so we have the difference in english between regular and irregular plurals and remember a plural is when there's more than one of something it comes from the Latin Plus which means more as opposed to the singular when there is just one of something you know one one dog two dogs so there's a handful of words in English and it really is a handful that don't PluralEyes regularly words like leaf and loaf and calf it's a baby cow if you try to pluralize these as though they were regular plurals you're gonna return something that is not correct or at least is not conventional within modern standard American English right so Leafs for example unless you're talking about the Toronto hockey team is not correct in fact the proper term boop-boo-boo-boop is in fact leaves it is not loafs but loathe tasty loaves of bread it is not calf's but calves so there are several different kinds of irregular plurals that's why this video is called part one but I'm only going to cover one such irregular plural today and that is the change from singular F to plural ve so if you see a word generally that ends in F the plural is going to become ve you can learn anything Dave it out
