What part of speech is the word such?

The word "such" can be several parts of speech, depending on its function in a sentence:

* Determiner: This is the most common usage. It modifies a noun, indicating a specific type or quality.

* Example: "I've never seen such beautiful flowers."

* Adjective: It can act as an adjective, often with the word "a" or "an" preceding it.

* Example: "He's such a good friend."

* Pronoun: In some cases, "such" can stand in for a noun phrase.

* Example: "The old books were dusty, and such were the shelves."

* Adverb: Less common, but "such" can modify an adjective or another adverb.

* Example: "He was such a talented musician."

It's helpful to look at the context of the sentence to determine the part of speech.
