I didn’t sleep last night AND the night before
My wife is a non-native speaker and came up with the phrase above. Rightly or wrongly - I gently suggested that I’d use OR instead of AND ie
“I didn’t sleep last night AND the night before”. --> “I didn’t sleep last night OR the night before”.
That’s based on the sound of it (I’m no expert). The second sentence sounds better to me, but makes no sense really. Why is it “OR”.
In fact I’d probably use a slightly difference sentence in written English (after multiple hacks), and don’t really care re verbal use.
But that’s not my my question. I’ve been wondering about the use of ‘AND’ and ‘OR’ in similar contexts. For example:
“I don’t like chocolate OR ice-cream” “I don’t like chocolate AND ice-cream”
“I don’t like chocolate OR vanilla ice-cream” “I don’t like chocolate AND vanilla ice-cream”.
I think there’s two issues here... the grouping of words, and the way in which OR somehow acts like AND.
The AND vs. OR bit particularly bothers me... Can somebody explain this? In math/logic they are opposite terms.
