Tezos name ancient greek roots etymology

Hello all just was super curious for the name origin in the wiki it mentions “Tezos” means smart contract in ancient greek.

Well I am Greek and I understand quite some Ancient greek.

I have a friend who showed me in the wiki that it has ancienct greek origins and I was surprised.

Could anyone say more for the exact etymology?

My guess is it either comes from :

thisia = sacrifice (exchange to gods) ?
or
thesi = position

but could be totally wrong so please if someone knows tell me.

Cheers
