When you use the word “few”, you are describing multiple things but as one group; the object of the sentence becomes singular, “a few weeks” and not “an few weeks”. So by using “few” you have turned weeks plural into a singular group of weeks, a “few” weeks. “Week” is a countable noun, but words like “few” and “some” are uncountable.

Hiya! They're not part of a class of words that can be classified as singular or plural. Matt

There are some good explanations here, but I agree with Matthew, they cannot be classified as plural or singular :)

Hi Mak, Another few weeks is correct because another refers to few here. Another is always used with singular nouns. It will help you to think of it as AN+other (a/an = one): Give me another apple (=one more apple) Other can be used with both singular and plural nouns: Close the other window, not this one (there are only two windows). I want other cherries, these are unripe.
