One who accepts carved teak? Right! (5)
I believe the answer is:
taker
'one who accepts' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'carved teak? right' is the wordplay.
'carved' indicates anagramming the letters.
'right' becomes 'r' (common abbreviation).
'teak' anagrammed gives 'take'.
'take'+'r'='TAKER'
Can you help me to learn more?
(Other definitions for taker that I've seen before include "Person seizing something" , "He accepts" , "Could be a thief" , "One getting possession (of something)" , "(Challenge) acceptor" .)
