Lascivious Latin in the same place is not finished with common sense (10)
I believe the answer is:
libidinous
'lascivious' is the definition.
(I know that lascivious can be written as libidinous)
'latin in the same place is not finished with common sense' is the wordplay.
'latin' becomes 'l'.
'in the same place' becomes 'ibid' (synonyms).
'not finished' means to remove the last letter.
'with' means one lot of letters go next to another.
'common sense' becomes 'nous' (nous is a kind of common sense).
'is' with its last letter removed is 'i'.
'l'+'ibid'+'i'+'nous'='LIBIDINOUS'
(Another definition for libidinous that I've seen is " lustful".)
