Like some clothing concealed by another malefactor (7)
I believe the answer is:
thermal
'like some clothing' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'concealed by another malefactor' is the wordplay.
'concealed by' indicates a hidden word.
'THERMAL' is hidden within 'another malefactor'.
Can you help me to learn more?
(Other definitions for thermal that I've seen before include "Type of air current" , "Warm like winter woollies" , "Warm or hot - underwear?" , "Concerned with high temperature" , "Designed to retain heat" .)
