Butterfly to ashi transition
Also known as Butterfly Ashi Garami — the canonical term used on this site.
Full name — butterfly-guard to ashi-garami transition
Butterfly to ashi transition is the full descriptive name for the butterfly-ashi sequence — the transition from butterfly guard to ashi garami leg entanglement.
Etymology. The compound phrase enumerates the starting position (butterfly) and the destination (ashi) with the transition mechanism between them. The full name predominates in published instructional vocabulary.
Mechanics. The transition shifts the attacker’s leverage from sweep-oriented butterfly hooks to leg-attack-oriented ashi garami — the same general leg-position serves both purposes through different commitment angles.
Cross-reference. “Butterfly ashi entry” and “Hook-to-thread conversion” are alternate names. Full mechanical coverage on Butterfly Ashi.
