How about dosage what part of speech?

"Dosage" can be several parts of speech, depending on how it's used in a sentence:

* Noun: This is the most common usage, referring to the amount of a medicine or drug to be taken at one time.

* Example: "The doctor prescribed a dosage of 500mg."

* Adjective: This usage is less common but can be used to describe something related to dosage.

* Example: "The dosage instructions are clear."
