The building blocks of English

Affixes

English words make use of a wide range of prefixes and suffixes — word beginnings and endings — to sharpen, extend, or transform meaning.

This dictionary contains more than 1,250 entries, illustrated by some 10,000 examples, all defined and explained. It’s based on Michael Quinion’s book Ologies and Isms: Word Beginnings and Endings, published by Oxford University Press, updated with new entries.
