In russian language if you say 'Нам нужны теплые вещи' it means that you need warm clothes, not things. 'Thing' is too abstract word for that case.
Thank you for explaining that...I wouldn't have known otherwise. ;-)
BTW, a tip for English speakers to remember тёплый: it has the same root as the English word "tepid."
English question (if I may) is tepid warmer or colder than lukewarm?
That's what I thought so thank you for confirming that!
Aaaah, I was just wondering about that. "What kind of things? Clothes? Hand warmers? Kittens?"
What tense is nam ( dative) ? And what tense is veshchee here ?
Verbs have tenses, nouns have cases. Нам is indeed dative (indirect object) and вещи is nominative (subject).
