Else is an adverb that is used to indicate an alternative choice or option different from what has been mentioned or specified previously. It refers to something or someone different or additional to the particular thing or person being referred to. It implies an option beyond the initially mentioned ones.

When used in a sentence, "else" introduces an alternative possibility, often contrasting with those already presented. It suggests an additional or different course of action or outcome. It is often used to emphasize the notion of difference, emphasizing that there is something distinct from the already mentioned options.

For example, in the sentence "I want to go to the movies, but if you have any other plans, I am open to doing something else," the word "else" conveys the idea that the speaker is willing to consider alternative activities beyond going to the movies.

"Else" can also be used as part of a phrase, such as "anything else" or "somebody else." In these instances, it emphasizes the inclusion of something or someone different or additional.

Overall, else is an adverb that signifies an alternative or additional choice, differing from what has been mentioned or specified previously. It underlines the presence of an alternative or supplementary option.
