nounapplied

Nounapplied is a proposed linguistic term describing a category of modifiers formed when a noun functions directly as a modifier within a noun phrase. In nounapplied usage, the modifying noun contributes semantic content such as material, type, or purpose, while the head noun remains the main reference. The construction is common in English and other Germanic languages and is often realized as noun-noun compounds or attributive noun phrases. It is distinct from attributive adjectives in that the modifier retains noun-like morphology and can take noun-specific inflection or plural marking in languages that permit it.

Examples include data analysis, stone wall, car engine, and chocolate cake. In these cases, the first noun acts as a modifier rather than as a secondary sentence element. In contrast, where an adjective is used (blue wall, delicious cake), the modifier is not noun-derived.

Cross-linguistic variation is notable: some languages allow productive noun modifiers with inflection, while others treat them as compounding with spacing, hyphenation, or reduplication rules. Functionally, nounapplied modifiers can express material (gold ring), type (plastic bottle), or purpose (driving wheel). They can also form longer chains (model airplane parts), yielding highly specific noun phrases.

The term is not universally adopted and is sometimes conflated with noun adjunct or denominal adjectives. Some scholars reserve nounapplied for clearer noun-derived modifiers when the modifier itself retains nominal properties.
