The genitive of measure in English Hello guys! I'm a bit confused with the genitive of measure. How would you say: " This three-floor villa is surrounded by beautiful gardens and (...)" OR " This three floors villa is surrounded by gardens and (...)" It is an example of the genitive of measure, right? I mean that kind of genitive which is used in expressions that indicate a measure (for example, distance or duration). With countable nouns ("year", for hence) we use this scheme: a three-year period. With uncountable nouns we use the noun in genitive+noun head, for example: two years' work experience. With both count. and uncount. nouns we can use both schemes: a two-week/two weeks advance notice. So, the noun in my phrase is countable. But it sounds strange to me to read "three-floor"... Help me, ple-e-e-ase! :)
