Distribute CV around plant that's out of service? (5)

'distribute cv around plant that's out of service?' is the definition.
I can't tell whether this defines the answer.

'cv around plant that's out of service?' is the wordplay.
'around' is an insertion indicator.
'plant' becomes 'ivy' (ivy is a plant).
'that's out' means to remove the last letter.
'of service?' becomes 'y' (I can't justify this - if you can you should believe this answer much more).
'ivy' with its final letter removed is 'iv'.
'cv' going around 'iv' is 'civv'.
'civv'+'y'='CIVVY'

Can you help me to learn more?
