Man, tense, embraced by man that’s near (6)
I believe the answer is:
mister
'man' is the definition.
(mister is a kind of man)
'tense embraced by man that's near' is the wordplay.
'tense' becomes 't' (grammatical abbreviation).
'embraced by' means one lot of letters goes inside another.
'man' becomes 'm' (M is an abbreviation for male or masculine).
'that's near' becomes 'iser' (I can't explain this - if you can you should give a lot more credence to this answer).
'm'+'iser'='miser'
't' inserted into 'miser' is 'MISTER'.
Can you help me to learn more?
(Other definitions for mister that I've seen before include "Mr" , "Set rim (anag.)" , "Merits of form of address to man" , "Male form of address" , "Bloke" .)
