what are the possesive and the plural possesive forms of the following words:
shelf
wrench
bus
Thank You
These are all semi-regular nouns. They're not completely irregular (i.e., child, man, woman, ox, etc.), but they don't form plurals by simply adding -s.
Think of each noun, regular or irregular, as having four forms:
desk (s), desk's (s. poss.)
desks (pl), desks' (pl. poss.)
So ... I'll do the first one for you:
shelf, shelf's
shelves, shelves'
Now ... how will you write the other three forms of the other two? If you're not sure, be sure to use a dictionary to find the plural -- http://www.dictionary.com
To find the possessive form of a noun, you usually add an apostrophe (') followed by the letter "s" to the end of the word. However, for nouns that already end in "s," you generally only add an apostrophe.
The possessive form of the word "shelf" would be "shelf's" because it does not end in "s." Therefore, you add an apostrophe "s" at the end.
The possessive form of the word "wrench" would also be "wrench's" because it does not end in "s."
The possessive form of the word "bus" would be "bus's" because it does not end in "s."
Now, for the plural possessive form, you first make the noun plural and then add the possessive apostrophe.
The plural form of "shelf" is "shelves." So, the plural possessive form of "shelf" would be "shelves'." The apostrophe is added after the final "s" because the noun is already plural.
The plural form of "wrench" is "wrenches." Therefore, the plural possessive form of "wrench" would be "wrenches'."
The plural form of "bus" is "buses." Thus, the plural possessive form of "bus" would be "buses'."
Remember, in English, there can sometimes be variations or exceptions to these rules. So, it's always a good idea to consult a grammar guide or dictionary for specific words and their possessive and plural possessive forms.
