18c Use standard idioms.

Idioms are speech forms that follow no easily specified rules. The English say “Bernice went to hospital,” an idiom strange to American ears, which are accustomed to hearing the in front of hospital. Native speakers of a language seldom have problems with idioms, but prepositions (such as with, to, at, and of) occasionally cause trouble, especially when they follow certain verbs and adjectives. When in doubt, consult a dictionary.
