Editing English plurals (section)

=== Plurals of numbers ===
The following rules apply to the plurals of numerical terms such as ''dozen'', ''score'', ''hundred'', ''thousand'', ''million'', and similar:
* When modified by a number, the plural is not inflected, that is, has no ''-s'' added. Hence ''one hundred'', ''two million'', ''four score'', etc. (The resulting quantitative expressions are treated as numbers, in that they can modify nouns directly: ''three dozen eggs'', although ''of'' is used before pronouns or definite noun phrases: ''three dozen of them/of those eggs''.)
* When not modified by a number, the plural takes ''-s'' as usual, and the resulting expression is not a number (it requires ''of'' if modifying a noun): ''I have hundreds'', ''dozens of complaints'', ''the thousands of people affected''. Although the word ''hundred'' is a number if and only if it is both modified by a number and modifies a number itself. ''three hundred thousand dollars''
* When the modifier is a vaguer expression of number, either pattern may be followed: ''several hundred (people)'' or ''several hundreds (of people)''.
* When the word has a specific meaning rather than being a simple expression of quantity, it is pluralized as an ordinary noun: ''Last season he scored eight hundreds'' [=scores of at least 100 [[run (cricket)|runs]] in cricket]. The same applies to other numbers: ''My phone number consists of three fives and four sixes''.
* Note the expressions ''by the dozen'' etc. (singular); ''in threes'' [=in groups of three] etc. (plural); ''eight sevens are fifty-six'' etc.
