In jungle, a match gives little light (5)
I believe the answer is:
gleam
'little light' is the definition.
(small source of light)
'in jungle a match' is the wordplay.
'in' indicates a hidden word.
'GLEAM' is hidden in the letters of 'jungle a match'.
'gives' is the link.
(Other definitions for gleam that I've seen before include "Brief show of soft light" , "Glow of light" , "Faint light; (quality) shine (in eyes)" , "Glint" , "Brightness" .)
