Being on the male side, it has point (5)

I believe the answer is:
spear
'being on the male side' is the definition.
'spear' can be an answer for 'side' (thesaurus). I'm unsure of the 'being on the male' bit.
'it has point' is the wordplay.
'it' becomes 'sear' (I can't explain this - if you can you should believe this answer much more).
'has' means one lot of letters goes inside another.
'point' becomes 'p' (abbreviation).
'sear' placed around 'p' is 'SPEAR'.
Can you help me to learn more?
(Other definitions for spear that I've seen before include "Long pointed weapon" , "Pole with pointed end" , "Sharp-tipped weapon" , "pierce with this?" , "Weapon to throw" .)
