It is not correct to say that "hair" can be used as  a  "plural" -- but that's sort of the right idea, because when you use the expression "haircut" your focus is not on the individual hairs, but on the whole collection.\n\nThe key to this is noting the difference between "count nouns" and "non-count" OR "mass" nouns, AND that there are some nouns that are sometimes used as one and sometimes as the other.\n\n1) MOST nouns are "count nouns" \nThat is, you can count them and speak of one, two, etc. \n \n2) Some nouns are "mass nouns"  which are not counted\n*furniture, stuff, weather, gold  \n\nNow note that using a mass noun does NOT mean that what you are discussing cannot be counted, only that the term itself cannot be used to count.\nThus you cannot say"I have one furniture" or "one stuff"; rather you must say "I have some furniture" or "I have a piece [or three pieces] OF furntiture".\n\na) Pure mass nouns (unlike the type listed below) do NOT have a plural form -- the grammatically "singular" form is used to refer to any amount.  (This is not, incidentally, the same as forms that happen to be the same in the singular and plural since those may still be count nouns, e.g., "one sheep, two sheep".)\n\nb) But other nouns  are used in SOME settings as "mass nouns" referring to a WHOLE ('the mass') or collective, and in other contexts may be used as "count nouns". \n*love, hair, fruit, soup, water, sugar\n\n"I'd like another bowl of soup."  vs.  "What soups are on the menu?"\n"My hair is a mess" (NOT 'hairs'), but "Where did these three blonde hairs on your suit come from?!"\n\nYou can tell that "hair" is being used as a mass noun in the way it takes the sort of constructions  noted above for mass nouns, such as "head OF hair" and "some hair" (vs. "few hairs" when they are counted individually).\n\nhttp://www.csmonitor.com/2004/1105/p18s03-hfes.html\nhttp://en.wiktionary.org/wiki/Talk:mass_noun

Because double letters are used for plurals in abreviations. For example, page is "p." while pages is "pp.". So Estados Unidos is "EE.UU."

It would be usual to say "equipment is".\n\nTheoretically we could say "equipments are" \nand the plural form is accepted in the Scrabble world.

"Clever clogs" is both the singular and the plural! It's like sheep. That's both singular and plural. Or trousers! You don't have one trouser (or at least I've never seen one!)

Because it is plural.  In spanish if you abbreviate something in plural you double the initial.

Look at your subject. The subj. in this sentence is "babies" which is plural. Therefore, the subject must agree in number with the verb. Your verb must then be the plural form "have."
