Etymology. ni- (down, into) + √dhā (to place, put), literally 'placed down' or 'deposit'. The prefix ni- suggests something stored away in a secure place. Cognate with Sanskrit nidhī and Greek thesis (a placing). The concrete spatial sense of 'putting down into a safe location' becomes the abstract notion of a repository or treasure.
