Paka sound meaning
Sound meaning of Pa+ka = More with + Gain (adding up + gain),
roughly it means..
lets see some words and see if the above meaning fits..
pakal – Day time
Pakkam – Near
Pakattu -To show off
Pakadai – A bait
Pakai – enemity ( here the ai, comes in for the restriction/possession, so pakai is restrict to give access)
Paku – Share (in the sense of showing/sharing it with many) Pakuthi – Part
Pakavan – God (I think in the meaning, one who can add up more, always embracing/affectionate)
If Paka – More gaining, surely Paaka should mean More unknown/cannot gain, literally cannot be taken more with.
