Hearing vowels in comfort (4)
I believe the answer is:
ease
'comfort' is the definition.
(I know that comfort can be written as ease)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ease that I've seen before include "Assuage" , "Lack of worry or agitation" , "composure" , "Lessen intensity" , "Soothe" .)
