Verb-forming suffix — “to make,” “to become,” “to cause to be,” “to subject to,” “to engage in”
The suffix entered English in the 1530s as authorize and civilize (verb), borrowed from French -iser, from Latin -izare, from Greek -ίζειν (-izein) — literally “to make” or “to cause to be.” The suffix is extremely productive in English, with hundreds of medical and technical compounds coined in the 1700s–1900s. The root -izō (“to make, to cause”) connects -ize to the entire verb-forming suffixes: immobilize (immobil- + -ize → to make immobile/fixed in place), stabilize (stabil- + -ize → to make stable/firm), and mobilize (mobil- + -ize → to make mobile/capable of movement). The verb-forming suffix-ize is one of the most productive suffixes in English medical and clinical terminology: e.g., immobilize, stabilize, mobilize, immobilize, and stabilize.
