Language in which to take leave, perhaps? (6)
I believe the answer is:
french
This clue might be a double definition.
'language in which' is the first definition.
'French' can be an answer for 'language' (French is an example). I am unsure of the remainder of the definition.
'leave perhaps?' is the second definition.
'French' can be an answer for 'leave' (thesaurus). I am not certain of the 'perhaps?' bit.
'to take' acts as a link.
Can you help me to learn more?
(Other definitions for french that I've seen before include "Take this leave without permission" , "The losers at Agincourt" , "- Cricket; - dressing" , "Shellac dissolved in alcohol, used on furniture" , "Continental language (Polish?)" .)
