The teachers at my rather prissy and genteel London girls’ primary school in the 1960s had an odd prejudice against the word. When any pupil used it in speech or writing we were rebuked, told it was a ‘meaningless’ word, and instructed to find a ‘better’ one, such as kind, friendly, delicious, pretty, comfortable, according to the context. That aways puzzled me. Granted, ‘nice’ in the usual modern sense is indeed a fairly vague term; but no more so than ‘agreeable’, which was one of the permitted substitutes. And I can’t recall any other vague word being pounced on in the same way.
Did anyone else encounter this prejudice at school, or anywhere else?
