We have had a few queries about this word and similar ones. RULE: Nouns which have regular plurals and which, in their singular form end with a consonant + y, form their plural by changing the y into an 'i' and adding 'es'. So * baby becomes babies * lady becomes ladies * party becomes parties * enquiry becomes enquiries * and query becomes ... queries.
Hmm... interesting question. I'm not sure it is just adding an s, but there are some noun forms that are singular when they end in S, and are plural when they end with something else. One of these groups are many nouns that end in -US. For instance, "octopi" is plural, and "octopus" is singular. So, it isn't just adding an s, but the s is one indicator that it is singular. Adding an apostrophe…
Singular possessives are formed by adding an apostrophe sto the end of a noun. For plural nouns that end in -s, the possessive are formed by adding an apostrophe after the existing -s; for irregular plural nouns that don't end with -s, the possessive is formed by adding theapostrophes the same as a singular noun.
Possession is shown by use of an apostrophe. A singular noun forms the possessive by adding an apostrophe s ('s) to the end of the word. A plural noun forms the possessive by adding an apostrophe (') after the ending s or adding an apostrophe s ('s) to the end of an irregular plural noun. The singular possessive form is: the boy's team. The plural possessive form is: the boys' team.
