I believe the answer is:

hold

I'm a little stuck... Click here to teach me more about this clue!

'grasp' is the definition.
(I know that grasp can be written as hold)

'husband when elderly' is the wordplay.
'husband when' becomes 'h' (abbreviation. I am not sure about the 'when' bit.).
'elderly' becomes 'old' (similar in meaning).
'h'+'old'='HOLD'

Can you help me to learn more?

(Other definitions for hold that I've seen before include "Clasp" , "Ship's cargo area" , "Grip" , "defend successfully" , "Continue" .)

I've seen this clue in The Mirror.
