Reveal occasionally sunny view I initially loved (6)
I believe the answer is:
unveil
'reveal' is the definition.
(I know that reveal can be written as unveil)
'occasionally sunny view i initially loved' is the wordplay.
'occasionally' means one should take alternating letters.
'initially' indicates taking the first letters.
The initial letter of 'loved' is 'l'.
'sunny'+'view'='sunnyview'
The alternating letters of 'sunnyview' are 'unve'.
'unve'+'i'+'l'='UNVEIL'
(Other definitions for unveil that I've seen before include "'Reveal, uncover (6)'" , "bare" , "Expose by removing covering" , "Introduce publicly for the first time" , "Uncover, disclose" .)
