Second course in meal, currently in vogue (6)
I believe the answer is:
modish
'in vogue' is the definition.
(synonyms)
'second course' is the wordplay.
'second' becomes 'mo' (both are short periods of time).
'course' becomes 'dish' (dish can mean a course of a meal).
'mo'+'dish'='MODISH'
'in meal currently' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for modish that I've seen before include "In vogue or fashion" , "I'm shod in the current fashion" , "in the latest fashion?" , "In fashion or style" , "Trendy" .)
