exact keyword domain in plural

Hello, I want to ask about making a keyword domain name. Does it matter if it is plural or not ?

For example, the good keyword I found is "word something review" (it gives a lot of exact match searches, but "word something reviews" in plural does not).

Can I choose a domain name where "reviews" is in plural ? domain will be word-something-reviews.com does it give same seo results ?

Also, I hate websites where domain name is three words separated with a "-", like word-something-reviews.com, but in SEO point of view, is that ok ?

Well I do know that G will return different results on words that are plural and not plural, depending on the market and keyword used. Some markets are more competitive than others and G will show much more different results.
