Gets somewhere concerning one's personal discomforts (7)
I believe the answer is:
reaches
'gets somewhere' is the definition.
I can't tell whether this definition defines the answer.
'concerning one's personal discomforts' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'one' becomes 'a' (a thing is one thing).
'personal discomforts' becomes 'ches' (I can't justify this - if you can you should believe this answer much more).
're'+'a'+'ches'='REACHES'
Can you help me to learn more?
(Other definitions for reaches that I've seen before include "Comes to" , "Attains" , "Gets to" , "Arrives at" , "Hands down" .)
