Butterfly ashi entry
Also known as Butterfly Ashi Garami — the canonical term used on this site.
Training background: entry route name rather than position name
Entry-context — butterfly-to-ashi transition
Butterfly ashi entry is the entry-context name for the butterfly-ashi position — the transitional configuration in which the attacker converts a butterfly hook into an ashi garami leg entanglement.
Etymology. “Butterfly ashi” specifies the position-family hybrid; “entry” attaches the transition-mechanism context. The compound predominates in instructional vocabulary that emphasises the entry-and-transition mechanic.
Mechanics. The butterfly hook destabilises the standing opponent’s leg structure; the transition to ashi garami commits the hip into the inside space before the opponent recovers the leverage.
Cross-reference. “Hook-to-thread conversion” and “Butterfly to ashi transition” are alternate names. Full mechanical coverage on Butterfly Ashi.
