Standing to join the French sailor (10)

I believe the answer is:

tolerating

'standing' is the definition.
('tolerate' can be a synonym of 'stand')

'to join the french sailor' is the wordplay.
'join' is a charade indicator (letters next to each other).
'the french' becomes 'le' ('the' in French).
'sailor' becomes 'rating' (British term for a naval enlisted man).
'to'+'le'+'rating'='TOLERATING'

(Another definition for tolerating that I've seen is " Wearing".)

I've seen this clue in The Daily Express.
