word choice - "Within the past year" vs. "In the past year" - English ...
Is it correct to say the following: Let this be a year where there will be joy. Or is there some more natural phasing for that sentiment in English?
3 7 months a year means 7 months for each/every year. "Per" in English is used to mean "for each". Therefore 7 months per year = 7 months for each year. 7 months out of a year just comes across as a clumsy way of saying it.
Ten year old may be used as an adjective, but only attributively ("a ten year old boy"). And your last sentence is back to front: ten years old is an adjectival phrase like brainy, while ten year olds is a noun phrase like a boy.
The word year when pronounced starts with a phonetic sound of e which is a vowel sound making it eligible for being preceded by an. Yet, we tend to write a year. Why?
I recommend "in the year 1908" then. It's hard to argue in any case that the year belonged to or derived from "1908", which would warrant the use of the word "of". AKA "Freud is a visitor at James's Sussex residence, Lamb House, in the land of ZOMBIES" would properly imply that the land was owned by or populated by zombies.
