Nouns derived from Adjectives

Some adjectives turn into nouns when attached to the suffix -th.

For some reason we won't discuss here, in this suffixation the root morpheme of the adjective is usually modified. And if the adjective ends with "e", the "e" disappears.

Here follow the most frequent examples of this process of word-formation:

strong - strength

broad - breadth

long - length

deep - depth

wide - width

true - truth

warm - warmth

There are also some adjectives that turn into nouns in an irregular process, following different rules of derivation. Here are some examples:

high - height

hot - heat

young - youth

grown - growth

dead - death
