We had a lot of kids round on Halloween for some mass trick-or-treating. Even when we split them up, the groups were too big. As we were strolling between houses, JessieL asked me 'what's this linguisty jobbie Apoa's been telling me about?'
She was referring to the utterance 'Everybody doesn't like chocolate'. My students find it hard to believe that for some speakers it can mean 'not everybody likes chocolate' as well as 'nobody likes chocolate' (I've got a feeling I agreed with them once - maybe I've been contaminated by linguists). I promised I'd ask a few more folk.
At breakfast, we found 3 out of 4 people accepted both senses. Apoa was the odd one out and just found it weird. JessieL was incredibly articulate as she explained her opinion to Apoa:
'Technically, like if you're talking proper and everything, it just means that every single person doesn't like chocolate. But I can see that some people might say it sometimes and mean that not everybody likes it.'
It's a good illustration of the problems of investigating competence when all of your evidence has to be based on performance data (at least that's what I tell the students).
