Left cigar perhaps - it has a pungent taste (6)
I believe the answer is:
garlic
'it has a pungent taste' is the definition.
The definition suggests a singular noun which matches the answer.
'left cigar perhaps' is the wordplay.
'left' becomes 'l' (common abbreviation).
'perhaps' indicates an anagram.
'l'+'cigar'='lcigar'
'lcigar' anagrammed gives 'GARLIC'.
Can you help me to learn more?
(Other definitions for garlic that I've seen before include "Pungent allium" , "Pungent bulbs" , "Pungent edible bulb" , "Aioli ingredient" , "Pungent-tasting bulb" .)
