Explanation
Either is a word used when talking about a choice between two things. For example, as a determiner (adjective) “You can have either tea or coffee” means you must pick one, or as a pronoun “Either of the books is fine for the assignment.” It can also mean “both sides” in some cases, like “Either side of the road had trees.” As an adverb, it can be used in negative sentences to mean “also” or “too”; for example, “I don’t like it either.” This word is common in daily conversation when making choices, comparisons, or agreements.
