A suffix is a type of affix — a bound morpheme that attaches to the end of a word stem to modify its meaning or grammatical function. Two parameters carve the construct: (1) position: the affix attaches after the stem (e.g. English -ness in happiness, -s in cats), which distinguishes it from prefixes (before the stem), infixes (inside the stem), and circumfixes (around both edges); (2) function: the suffix contributes either derivational content (creating a new lexeme, e.g. -ness turning 'happy' into 'happiness') or inflectional content (marking grammatical relations without changing lexeme identity, e.g. -s marking plural on cats). Suffixes persist as a productive morphological resource: speakers attach them productively in their language, and grammars catalog them as part of the affix inventory.

Suffix is a type of affix that attaches to the end of a word stem. Removal test (Laws 8/8b): remove the concept of stem — the host material the suffix attaches to — and suffix loses its operational meaning. A suffix is defined by its attachment to a stem; without stem, suffix is an unanchored bound morpheme. Constitutive dependency.
- affixINSTANCE_OF →
A suffix is a specific kind of affix — one distinguished by its attachment position after the stem. The accepted definition of affix explicitly lists 'suffixes (-ness, -s)' as a type. A competent morphologist calls a suffix 'an affix' (the suffixal variety). Nearest kind: affix is the nearest accepted kind (no intermediate kind exists on the board between suffix and affix). Pinned sense (Law 11d): suffix as the affix type, per its own accepted definition.
