what do they mean? "impeccably attired" "painfully obvious" "perfectly plain"
I did a collocation exercise today. and the following is the answer.
now look at the first, attired, does it mean clothes, is its meaning well-dressed?
painfully obvious, what's the meaning painfully? can you give me a sentence to illustrate its meaning?
perfectly plain, what's the meaning of plain? please give me example sentence.
thanks a lot,
by the way,
please look at the following sentences:
1, In what country was he born?
2, What country was he born in?
these two sentences, which one is formal? which one is informal? why?
