'redirectible' originates from Modern English, specifically formed from the verb 'redirect' plus the suffix '-ible', where 're-' (from Latin) meant 'again', 'direct' (from Latin 'directus') meant 'to guide/lead', and the suffix '-ible' (from Latin '-ibilis') meant 'able to be'.

'direct' came from Latin 'directus', passed into Old French as 'direct' and then into Middle English as 'direct'; adding the prefix 're-' produced 'redirect' in English, and the Latin-derived adjectival suffix '-ible' was later attached to create 'redirectible' in modern English usage.

Initially formed to mean 'able to be redirected' (the literal compositional meaning), and it has retained that core sense in current technical and general use.
