This document discusses various morphological processes in English, including concatenative processes like compounding, affixation, reduplication, and non-concatenative processes like internal modification, conversion, and back formation. It provides examples for each process and explains how they change word meanings or word classes. Compounding combines words, affixation adds prefixes or suffixes, reduplication repeats parts of words, and internal modification changes vowels, consonants, stress, or tones. Conversion changes a word's class without altering form, while back formation derives a new word class from an existing form.
