Time for Lima to send up language (5)
I believe the answer is:
tamil
'language' is the definition.
(Tamil is an example)
'time for lima to send up' is the wordplay.
'time for' becomes 't' (I've seen this in other clues).
'to send up' says the letters should be written in reverse.
'lima' backwards is 'amil'.
't'+'amil'='TAMIL'
(Other definitions for tamil that I've seen before include "One in race" , "Asian language" , "Native of south India or Sri Lanka" , "Sri Lankan" , "Perhaps Indian" .)
