An archaic or specialized legal term referring to cautionary measures, security, or a pledge held as a guarantee.
From 'caution' plus the suffix '-ery' (forming abstract nouns or collections), an older English formation similar to 'machinery' or 'pottery,' used especially in Scottish and medieval legal terminology.
In Scottish legal history, 'cautionry' referred to money or goods pledged as security for a loan—it's a word that survived in one legal system while disappearing elsewhere, showing how legal language branches into different national variations.
