I am needing bit of time, behind schedule -- sacrifice to be made (8)
I believe the answer is:
immolate
'schedule sacrifice to be made' is the definition.
I can't judge whether this defines the answer.
'i am needing bit of time behind' is the wordplay.
'i am' becomes 'im'.
'needing' is a charade indicator (letters next to each other).
'bit of time' becomes 'mo' (mo can mean a short period of time).
'behind' becomes 'late'.
'im'+'mo'+'late'='IMMOLATE'
Can you help me to learn more?
(Other definitions for immolate that I've seen before include "Destroy; burn" , "Sacrifice, kill or destroy" , "Offer as sacrifice (usually by burning)" , "Limo team involved in sacrifice" .)
