Greek character with drink on the counter shows taste (6)
I believe the answer is:
palate
'taste' is the definition.
(I've seen this before)
'greek character with drink on the counter' is the wordplay.
'greek character' becomes 'eta' (letter from the Greek alphabet).
'with' means one lot of letters go next to another.
'drink on' becomes 'lap' (lapping is a kind of drinking. I am not sure about the 'on' bit.).
'the counter' is a reversal indicator.
'eta'+'lap'='etalap'
'etalap' backwards is 'PALATE'.
'shows' acts as a link.
Can you help me to learn more?
(Other definitions for palate that I've seen before include "One may savour" , "where taste is considered" , "Sense of taste at roof of mouth" , "having ability to appreciate good food" , "relish" .)
