Put up with tedious fellow, man finally restricted (5)
I believe the answer is:
borne
'put up with tedious' is the definition.
I can't tell whether this definition defines the answer.
'fellow man finally restricted' is the wordplay.
'fellow' becomes 'bore' (I can't explain this - if you can you should give a lot more credence to this answer).
'finally' indicates one should take the final letters.
'restricted' means one lot of letters goes inside another.
The last letter of 'man' is 'n'.
'bore' placed around 'n' is 'BORNE'.
Can you help me to learn more?
(Other definitions for borne that I've seen before include "Carried or endured" , "Produced" , "Carried, conveyed" .)
