Suffixes 1 words

deriv suffix

Core Rule

Derivational suffixes create new words by changing meaning or part of speech, such as -ness, -tion, -able. They expand vocabulary rather than mark grammar. Stress usually stays on the root, while suffixes are weakly stressed.

Pronunciation Guide

Most derivational suffixes contain a schwa /ə/ or short vowel. Keep the tongue relaxed and centered, mouth slightly open, and airflow smooth. Avoid over-pronouncing letters.

Word Analysis

happy → happiness (Adj → Noun, -ness /nəs/); educate → education (-tion pronounced /ʃən/, a normalized sound change).

Pitfall Alert

Do not pronounce suffixes letter by letter. Watch for spelling changes like y → i before adding suffixes.
