Dear all,
I am trying to understand the difference between "two year period" and "two years period" or "tow-year period". I am not sure I understand when to use one and when to use the other one or which one is correct/wrong.
So far, to what I saw on the internet "two year" it should be a compound words therefore, it should be written using a hyphen "two-year" or is it not the case? However, I thought that when we are talking about many years we use the plural form. This is the part which is not clear to me why it should not be "two years period" or maybe "two-years period" instead of "two year period"? Is this because I am talking about one period of time of 2-year/-s?
(Here is the sentence I was talking about:
A longitudinal study was conducted over a two year period.)
A second question, is there a rule when two-year is a compound word and when not? When do I need to use the the hyphen and when not?
For example if I want to say: I met him two years ago. Is it correct to write without hyphen or with?
Any comments are highly appreciated.
Thank you!
