Lively quote grand Frenchman served up (9)
I believe the answer is:
energetic
'lively' is the definition.
(associated in meaning)
'quote grand frenchman served up' is the wordplay.
'quote' becomes 'cite' (synonyms).
'grand' becomes 'g' (G is short for grand as in a thousand).
'frenchman' becomes 'rene' (common French name).
'served up' shows that the letters should be reversed in order (in a down clue, going upwards).
'cite'+'g'+'rene'='citegrene'
'citegrene' backwards is 'ENERGETIC'.
(Other definitions for energetic that I've seen before include "Brisk" , "'Animated, full of life (9)'" , "Vigorous and dynamic" , "Lively, spirited" , "Full of beans" .)
