English to abandon championing of marriage (7)

I believe the answer is:

spousal

'marriage' is the definition.
(I've seen this before)

'english to abandon championing' is the wordplay.
'english' becomes 'e' (abbreviation).
'to abandon' is a deletion indicator.
'championing' becomes 'espousal'.
'espousal' with 'e' removed is 'SPOUSAL'.

'of' is the link.

(Another definition for spousal that I've seen is " Relating to a marriage partner".)

I've seen this clue in The Guardian.
