Little person stays cold, not hot, to make economies (6)
I believe the answer is:
scrimp
'make economies' is the definition.
(I've seen this before)
'little person stays cold not hot' is the wordplay.
I cannot quite understand how this works, but
'person' could be 'crimp' (crimp is a kind of person) and 'crimp' is present in the answer.
A single letter 's' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for scrimp that I've seen before include "Keep short" , "Be economical, mean, with" , "Make too small, stint" , "Be thrifty and parsimonious" , "Live meagrely" .)
