This, outside, right on the street, is lacking water (7)
I believe the answer is:
thirsts
'is lacking water' is the definition.
I can't tell whether this defines the answer.
'this outside right on the street' is the wordplay.
'outside' is an insertion indicator.
'right' becomes 'r' (abbreviation).
'on' is a charade indicator (letters next to each other).
'the street' becomes 'st' (abbreviation).
'r'+'st'='rst'
'this' placed around 'rst' is 'THIRSTS'.
Can you help me to learn more?
(Other definitions for thirsts that I've seen before include "Cravings" , "needs water" , "Hungers!" .)
