Jargon given latitude in turn (5)
I believe the answer is:
lingo
'jargon' is the definition.
(I know that jargon can be written as lingo)
'given latitude in turn' is the wordplay.
'given' says to put letters next to each other.
'latitude' becomes 'L' (abbreviation for latitude).
'turn' becomes 'go' (a person's move in a board game).
'l' put next to 'in' is 'lin'.
'lin'+'go'='LINGO'
(Other definitions for lingo that I've seen before include "Jargon, foreign language (informal)" , "Language (slang)" , "Johnny Foreigner speaks one" , "French?" , "means to communicate" .)
