Beginning, in Ohio, to equip home (6)
I believe the answer is:
origin
'beginning' is the definition.
(origin is a kind of beginning)
'ohio to equip home' is the wordplay.
'ohio' becomes 'o'.
'to equip' becomes 'rig' (rigging is a kind of equiping).
'home' becomes 'in' ('he's home' can mean 'he's in').
'o'+'rig'+'in'='ORIGIN'
'in' acts as a link.
(Other definitions for origin that I've seen before include "Where X meets Y" , "Source, derivation" , "For a start" , "extraction" , "Beginning, starting point" .)
