Yearned to sit around, getting rid of uniform with daft cap (6)
I believe the answer is:
longed
'yearned' is the definition.
('long' can be a synonym of 'yearn')
'sit around getting rid of uniform with daft cap' is the wordplay.
'sit around' becomes 'lounge' (lounge around).
'getting rid of' indicates named letters should be taken away.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'with daft cap' becomes 'd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'lounge' with 'u' removed is 'longe'.
'longe'+'d'='LONGED'
'to' acts as a link.
(Other definitions for longed that I've seen before include "Hankered, yearned" , "Had a yen" , "Desire strongly" , "Desired strongly" , "Thrust forward as with sword" .)
