The '-ness' Suffix: How It Works

Before exploring the complete lists, understanding how the '-ness' suffix functions grammatically and historically provides a foundation that makes the whole category easier to learn and use.

What Does '-ness' Do?

The suffix '-ness' is a derivational suffix. It attaches to adjectives (and occasionally to other word classes) and converts them into abstract nouns. The resulting noun names the quality, state, or condition described by the original adjective.

Adjective	Noun formed with '-ness'	Meaning of the noun
kind	kindness	the quality of being kind
dark	darkness	the state of being dark
aware	awareness	the condition of being aware
fit	fitness	the state of being fit
lonely	loneliness	the quality of being lonely
conscious	consciousness	the state of being conscious

Spelling Rules for Words Ending in Ness

Several spelling rules apply when adding '-ness' to adjectives to form words ending in ness. Understanding these rules prevents the most common spelling errors.

Rule 1: Most Adjectives Simply Add '-ness'

The most straightforward case: the adjective ends in a consonant or a vowel other than Y, and '-ness' is added directly.

dark + ness = darkness
kind + ness = kindness
aware + ness = awareness
fit + ness = fitness
bright + ness = brightness
calm + ness = calmness

Rule 2: Adjectives Ending in Y Change Y to I before Adding '-ness'

When an adjective ends in a consonant followed by Y, the Y changes to I before '-ness' is added.

happy → happi + ness = happiness
lonely → loneli + ness = loneliness
busy → busi + ness = business
heavy → heavi + ness = heaviness
lazy → lazi + ness = laziness
empty → empti + ness = emptiness
ready → readi + ness = readiness
worthy → worthi + ness = worthiness

Rule 3: Adjectives Ending in a Silent E Retain the E

Unlike some other suffixes (such as '-ing'), '-ness' does not drop a final silent E.

aware + ness = awareness (not awarness)
like + ness = likeness (not likness)
lone + ness = loneness
whole + ness = wholeness

Rule 4: Double Consonants are Not Added

When '-ness' is added, the final consonant of the adjective is not doubled, even when the adjective ends in a single consonant preceded by a single vowel.

thin + ness = thinness (the N is already doubled by the joining of thin + ness)
ill + ness = illness (the L is already doubled)
dull + ness = dullness
