I believe the answer is:

extol

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

'praise one's' is the definition.
'extol' can be an answer for 'praise' (extolling is a kind of praising). I'm unsure of the 'one's' bit.

'former spouse maybe a lot' is the wordplay.
'former spouse' becomes 'ex' (an ex-spouse).
'maybe' indicates anagramming the letters.
'lot' is an anagram of 'tol'.
'ex'+'tol'='EXTOL'

Can you help me to learn more?
