One who can always be counted on to repeat the party line with great gusto.
To make smooth or glossy by or as if by rubbing; polish.
The immediate and involuntary repetition of words or phrases just spoken by others, often a symptom of autism or some types of schizophrenia.
The branch of theology that is concerned with the end of the world or of humankind.
Of or relating to semantics.
