No, ‘other’ is not a preposition. It is primarily classified as an adjective.
‘Other’ is used to describe something that is different from the one already mentioned or known. For example, in the sentence ‘I prefer the other option,’ ‘other’ modifies ‘option’ and indicates a distinction between two or more choices.
Prepositions, on the other hand, are words that show relationships between nouns (or pronouns) and other words in a sentence, often indicating direction, location, or time. Examples of prepositions include ‘in,’ ‘on,’ ‘at,’ ‘between,’ and ‘under.’
Therefore, while ‘other’ plays an important role in sentence structure, it does not function as a preposition.
