Streams. (Emphasis on the "S")
As a collective noun, it's both singular and plural.
The "s" is there because it is plural. Such as, you and I, we are friends. To use it in a non plural would be something like : "I am a friend to him."
You would use s and not es, but this is not the way to make the word plural. You would use apostrophe s to indicate possession. For example, the child's illness had the whole family worried. The plural of child is children.
If a plural noun ends with an -s, just add the apostrophe after the ending -s (s').If a plural noun does not end with an -s (an irregular plural), add the apostrophe -s ('s) the same as for a singular noun. Examples:man; men; men'schild; children; children'sdeer; deer; deer'stooth; teeth; teeth's
The plural of URL is URLs (acronyms use a lowercase S to form plurals).
An 's preceded by an apostrophe ('s) indicates possession or contraction (e.g., John's book, it's raining). An s followed by an apostrophe (s') is used for plural possessives where the noun is already plural (e.g., the girls' toys).
The surname would normally just use an S to form the plural. But names that end in S, or that would be confused with those that end in S, add ES.
Not if it is a simple plural. Simple plurals do not require an appostrophe.
In the case of the possessive apostrophe, it is 's in the singular and s' in the plural use.
