Putting out a lot for life, almost in charge (8)
I believe the answer is:
prolific
'putting out a lot' is the definition.
(I've seen this in another clue)
'for life almost in charge' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'almost' means to remove the last letter (most of the word but not all of it).
'in charge' becomes 'ic' (abbreviation for 'in charge').
'life' with its final letter removed is 'lif'.
'pro'+'lif'+'ic'='PROLIFIC'
(Other definitions for prolific that I've seen before include "Very fertile, productive" , "Copious" , "having many children" , "Producing a great amount, as writer may" , "Plentiful" .)
