trinqueta 15
It is a feminization of ratchet, in the case of the "bow nautical sail" because it is feminine and because it goes in the ratchet ("sailboat stick"), and in others as the "clasp or clamp to hold the clothes" to differentiate it from the mechanical ratchet to lock gears, since this also lashing (lock), but the fabrics to a rope to pray them.
