-ness suffix

Core Rule

-ness is a productive noun-forming suffix added to adjectives to express a state, quality, or degree (e.g., kind → kindness). Orthographically, it is usually attached directly. When an adjective ends in -y, change y to i (happy → happiness). Phonologically, -ness is unstressed and consistently pronounced /nəs/.

Pronunciation Guide

Articulate /n/ with the tongue tip at the alveolar ridge and nasal airflow, glide into a reduced schwa /ə/ with a relaxed jaw, then release a light /s/. Keep the suffix short and weak; do not assign stress.

Example Analysis

kindness /ˈkaɪnd.nəs/ carries primary stress on the base. Contrast with buddhist and materialist: these take -ist, forming agent nouns (people or adherents), not abstract qualities—an essential semantic distinction.

Pitfall Prevention

Do not confuse -ness with -less (meaning “without”). Avoid over-pronouncing the vowel or shifting stress to the suffix. Watch spelling changes with final -y.
