The act or state of abiding; the practice of remaining in a place, sticking to an agreement, or continuing in a condition.
From abide (verb) plus -ance suffix (forming abstract nouns denoting state or action). The -ance suffix typically follows French-influenced verbs, contrasting with -ence forms.
Abidance is grammatically regular but sounds archaic—we now prefer 'abiding' as a noun or gerund, showing how English gradually consolidates its noun-forming suffixes, with some (-ance, -ence) becoming rarer while -ing becomes dominant.
