What is the meaning of "snuggled up warm" in the following sentence,
We were all cosy, snuggled up warm
?
Does it mean "We were all cosy and we snuggled up and we were warm" ? or does it mean "We were all cosy and we snuggled up in order to be warm" ?
Can we use the adjective "warm" instead of a noun behind the preposition "up"?
Grammatically, I have thought nouns came after prepositions. But, I often have seen many sentences with adjectives after prepositions. Is there a rule to make a sentence like this?
