Coax husband at last into circle with relative at the end (7)
I believe the answer is:
wheedle
'coax' is the definition.
('wheedle' can be a synonym of 'coax')
'husband at last into circle with relative at the end' is the wordplay.
'at last' says to take the final letters.
'into' means one lot of letters goes inside another.
'circle with' becomes 'wheel' (I can't justify this - if you can you should believe this answer much more).
'at the end' suggests the final letters.
The final letter of 'husband' is 'd'.
The final letter of 'relative' is 'e'.
'd' put into 'wheel' is 'wheedl'.
'wheedl'+'e'='WHEEDLE'
Can you help me to learn more?
(Other definitions for wheedle that I've seen before include "Inveigle using sweet-talk" , "Seek to persuade" , "Obtain by coaxing" , "Entice by soft words" , "Wheeled around to coax" .)
