Hendiadys

Hendiadys (/hɛnˈdaɪ.ədᵻs/; a Latinized form of the Greek phrase ἓν διὰ δυοῖν, hèn dià duoîn, "one through two") is a figure of speech used for emphasis — "The substitution of a conjunction for a subordination". The basic idea is to use two words linked by the conjunction "and" instead of the one modifying the other.
