Weak, working for company? (6)
I believe the answer is:
infirm
'weak' is the definition.
(I know that weak can be written as infirm)
'working for company?' is the wordplay.
'working for' becomes 'in' (I can't explain this - if you can you should believe this answer much more).
'company?' becomes 'firm' (firm can mean a company or business).
'in'+'firm'='INFIRM'
Can you help me to learn more?
(Other definitions for infirm that I've seen before include "not so healthy" , "Doddery" , "unstable" , "Not physically strong" , "Sickly" .)
