Able to be officially recognized or approved, often in relation to qualifications or institutions.
The institution is recognized as an accreditable body by the national education board.
Accreditable is formed from "accredit" (from Latin "accreditare", meaning to give credit to) and the suffix "-able" (meaning capable of). The word "accreditable" means capable of being given credit or recognized for something.
Think of being 'capable of receiving credit' — 'accredit' means to give credit, and '-able' means capable.
