Not able to stretch in laciest outfit (9)
I believe the answer is:
inelastic
'not able' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'stretch in laciest outfit' is the wordplay.
'in laciest' can be anagrammed to 'INELASTIC'.
However, I'm unsure how this is indicated.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for inelastic that I've seen before include "Lacking spring" , "Firm, not springy" , "Without a spring" , "lacking resilience" , "Supply not sensitive to price changes" .)
