Free from strain, though ultimately this bald? (10)
I believe the answer is:
stressless
'free from strain' is the definition.
The definition suggests a singular noun which matches the answer.
'ultimately this bald?' is the wordplay.
'ultimately' suggests the final letters.
'bald?' becomes 'tressless' (I've seen this in another clue).
The final letter of 'this' is 's'.
's'+'tressless'='STRESSLESS'
'though' acts as a link.
Can you help me to learn more?
(Other definitions for stressless that I've seen before include "Free from pressure or tension" , "without accent?" .)
