Gusset, (fr. gousset, the armpit): this truncation of the shield, like the gore, occurs usually on either the dexter or sinister side. In the former case(when sanguine) it is imagined to be an abatement for adultery, in the latter for drunkenness. Gussets, however, occur as honourable charges. When in base, the term graft seems preferable.
