Non-modifier

A 'non-modifier' in grammar refers to a word or phrase that cannot be altered by the addition of modifiers (adjectives or adverbs) without fundamentally changing or destroying the original meaning or grammatical function. Essentially, non-modifiers are considered absolute. They function as complete units conveying a specific meaning that is not open to degrees or variations. Common examples include words representing absolutes (like 'perfect' or 'unique'), certain prepositions, and sometimes numerals, particularly when denoting an exact quantity, or pronouns such as "I" or "he" that are not open to modification. Trying to modify them usually creates an illogical or grammatically incorrect sentence. They maintain a fixed role within a sentence. In the context of language models, identifying non-modifiers is crucial for accurately parsing and interpreting user intent.

Non-modifier meaning with examples

• 1. The painting was *unique*. One can not say "very unique" or "somewhat unique". It either *is* unique or it is not. Using modifiers like "very" doesn't augment the quality but it is illogical because it changes the sentence. This example is used to describe the absoluteness of the description which is not something open to gradations or comparisons. This is often considered an example of a non-modifier.
• 2. She lives *beside* the river. Modifying the preposition 'beside' with an adverb like "very" is illogical, as there are no degrees of 'beside'. Adding 'beside' to the sentence adds information about the location. It is used to provide relation of her location and not provide information about the noun itself, making it an example of a non-modifier.
• 3. He has exactly *five* apples. While you *could* write "five" with a modifier, such as "approximately", it changes the essential meaning of the numeral. The statement is an exact quantity of apples. The modifier will change this quantity but the meaning is still retained when the example includes the use of "exactly".
• 4. *Here* is the book you wanted. Trying to modify 'here' (an adverb) with an adverb of degree (e.g., 'very here') results in an awkward or nonsensical phrase. It is a non-modifier because it provides a clear indication of location without being capable of gradations. This can be considered a non-modifier.
• 5. *Perfect* attendance is required. One cannot have 'very perfect' attendance. The word implies an absolute state. Modifying it renders the adjective illogical in this context. This is often seen as one of the common and clear examples of a non-modifier. "Perfect" implies the absence of errors.
