Couples getting approval inside and outside (5)
I believe the answer is:
yokes
'couples' is the definition.
('yoke' can be a synonym of 'couple')
'approval inside and outside' is the wordplay.
I cannot quite see how this works, but
'approval' could be 'ok' (OK is an example) and 'ok' is located in the answer.
The remaining letters 'yes' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for yokes that I've seen before include "couples" , "Harnesses (oxen)" , "Harnesses together" , "Crosspieces fastened over the necks of a pair of draft animals" , "Oppresses" .)
