Is the word seldom a intensifier or interrogative noun acting as an adverb negative?

The word "seldom" is not an intensifier. It is an adverb of frequency that indicates something happens rarely or infrequently.

Here's why:

* Intensifiers make the meaning of a word stronger. For example, "very" or "extremely" are intensifiers. "Seldom" doesn't increase the strength of another word; it expresses how often something occurs.

* Interrogative nouns are used to ask questions (e.g., "who", "what", "where"). "Seldom" is not a question word.

* Adverb negative indicates a negative or absence of something (e.g., "never", "not"). While "seldom" implies a lack of frequent occurrence, it's not directly a negative adverb like "never".

Therefore, "seldom" is a frequency adverb that signifies infrequency.
