Alphabetical list of some important terms the Buddha redefined.
brahman: redefined as an Arahant. "That's not a Brahman. THIS is a brahman."
pre Buddhist meaning: one of the castes in India, the priest class.
metta: friendly-kindness, has absolutely no element of lust, romantic love.
Pre Buddhist: who knows exactly how the 4 brahmaviharas were in detail? But we do know that rebirth there for a non-buddhist would fall to lower realms on their next rebirth. And we also know beings there have no gender, don't breathe, don't have sexual reproduction, so Sujato's tainted "love" has no place in pre-Buddhist metta either. Probably pre-buddhist metta was a devotional emotion for a god, or host of gods.
✅ earned-trust, justified-confidence, provisional-trust. See how saddha is earned in MN 95, and revoked if unjustified
pre Buddhist meaning: perhaps something closer to the 'blind faith' that we typically see in many religions.
