Re: conjunction I didn't say it had to be positives and/or negatives- I said it had to be two ideas that were the same in some way. The positive and negatives of the examples were only an example. These two adjectives are the same because : tall = a physical quality; thin = a physical quality. They are two physical qualities.
Unqualified, as in your sentence, there is no way of telling whether they are positive or negative qualities - which is something entirely subjective. As you say, it is "in your opinion". For you, thin may be negative. For me it's very positive. So you would need to qualify it with an adverb to make your opinion clear. Compare :
Mike is tall and thin (neutral - two physical qualities co-ordinated)
Mike is very goodlooking, but he's horribly thin. (positive + negative qualities)
Mike is ridiculously tall and horribly thin (negative + negative qualities)
I wish I looked like Mike. He's really tall and wonderfully thin. (positive + positive qualities)
Mike is tall, but he's much too thin. (neutral + negative qualities) |
