Part of a meet for all to see followed by a learner after a time (8)
I believe the answer is:
eventual
'after a time' is the definition.
(I've seen this before)
'part of a meet for all to see followed by a learner' is the wordplay.
'part of a meet' becomes 'event' (I've seen this in another clue).
'for all' becomes 'U' (Universal film certificate - suitable for all).
'to see followed by' is a charade indicator (letters next to each other).
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'event'+'u'+'a'+'l'='EVENTUAL'
(Other definitions for eventual that I've seen before include "Ultimately resulting" , "'Inevitable, with time (8)'" , "Happening at the end of a period of time" , "Net value (anag.)" , "Coming at last, ultimate" .)
