-ness suffix
Core Rule
-ness is a productive derivational suffix forming abstract nouns from adjectives, denoting state or quality. It usually attaches directly (kind → kindness). Adjectives ending in -y change to -i (happy → happiness).
Pronunciation Guide
Pronounced /nəs/ or /nes/ with weak stress. Alveolar /n/ followed by a short, reduced vowel; airflow is light and brief.
Example Analysis
kindness, darkness show regular derivation. Contrast nationalist: built from nation + -al + -ist (person/ideology), so -ness is not used here.
Pitfalls
Watch spelling shifts (-y → -iness) and avoid confusing -ness with -ity or -ism.
