Happy to see a learner relaxed after a poor start (7)
I believe the answer is:
pleased
'happy' is the definition.
(similar in meaning)
'learner relaxed after a poor start' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'relaxed' becomes 'eased' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'start' indicates taking the first letters.
The initial letter of 'poor' is 'p'.
'l'+'eased'='leased'
'leased' after 'p' is 'PLEASED'.
'to see a' acts as a link.
(Other definitions for pleased that I've seen before include "Well satisfied" , "Glad" , "Grateful, delighted" , "like Punch?" , "Content" .)
