Time taken by a number to comprehend good Latin American dance (5)
I believe the answer is:
tango
'latin american dance' is the definition.
(I've seen this in another clue)
'time taken by a number to comprehend good' is the wordplay.
'time' becomes 't' (abbreviation).
'taken by' means one lot of letters go next to another.
'number' becomes 'no' (abbreviation).
'to comprehend' is an insertion indicator (comprehend can mean to contain or include).
'good' becomes 'g' (abbreviation).
'no' enclosing 'g' is 'ngo'.
't'+'a'+'ngo'='TANGO'
(Other definitions for tango that I've seen before include "Movement from Argentina" , "Ballroom dance (for two?)" , "Tonga (anag.)" , "musical piece" , "one followed by uniform" .)
