Butterfly half guard
Also known as Half Butterfly Guard — the canonical term used on this site.
Hybrid — butterfly hook with half guard
Butterfly half guard is the hybrid configuration name for the half-butterfly — using reversed-order naming compared to “half guard butterfly” but pointing at the same combined-mechanism position.
Etymology. “Butterfly” specifies the inserted-hook element first; “half guard” specifies the trapped-leg element second. The reversed-order naming appears in coaching contexts that emphasise the butterfly element as the primary leverage source.
Mechanics. The hook-plus-trap configuration combines elevation leverage (butterfly) with leg control (half guard) — the position produces sweep options that neither pure form supports.
Cross-reference. “Half guard butterfly” is the same hybrid under standard-order naming. Full mechanical coverage on Half Butterfly.
