requerible

Requerible is an adjective used to describe something that can be required or mandated by rules, processes, or systems. In practice, it denotes a property that supports being designated as required while preserving the possibility of being optional in other contexts. The term is not widely used in everyday English and is mostly found in technical or theoretical discussions. Alternative terms such as required, mandatory, or obligatory are generally more common.

Etymology and variants: Requerible is formed from the verb require plus the -able suffix. Spelling variants include requirable, requireable, and, less commonly, requerable. Most style guides prefer standard terms like required or required-to-be, but requerible may be used in specialized texts to emphasize the potential for obligation rather than immediate imposition.

Computing and data modeling: In software engineering and data validation, a property described as requerible indicates it can be mandated by business rules or by a validation schema. For example, a form field labeled as requerible is expected to be filled in for successful submission; omitting it typically triggers a validation error or a halt in processing.

Law and contract terminology: In legal drafting, a concept similar to requerible may describe obligations that may be invoked under certain conditions. However, requerible is not standard legal jargon and is usually replaced with terms such as required, mandatory, or subject to specified conditions.
