With words of acceptance, married: later so alone (7)

Ross

I believe the answer is:

widowed

'later so alone' is the definition.
(alone after the death of a spouse)

'with words of acceptance married' is the wordplay.
'with' becomes 'w' (abbreviation).
'words of acceptance' becomes 'I do' (vow said to accept a husband or wife).
'married' becomes 'wed' (similar in meaning).
'w'+'ido'+'wed'='WIDOWED'

(Another definition for widowed that I've seen is " Having lost one's spouse".)

I've seen this clue in The Guardian.
