'what it takes to be a bigamist' is the definition.
I can't tell whether this defines the answer.

'points out i have' is the wordplay.
'points' becomes 'ws' (W is an example).
'out' indicates putting letters inside.
'i have' becomes 'I've' (contraction of 'I have').
'ws' enclosing 'ive' is 'WIVES'.

Can you help me to learn more?

(Other definitions for wives that I've seen before include "Spouses" , "Men's partners in marriage" , "See 11" .)
