Yearns for lengthy summer, initially (5)

I believe the answer is:

longs

'yearns' is the definition.
(I know this)

'lengthy summer initially' is the wordplay.
'lengthy' becomes 'long' (synonyms).
'initially' indicates taking the first letters.
The first letter of 'summer' is 's'.
'long'+'s'='LONGS'

'for' is the link.

I've seen this clue in The Mirror.
