Here's why:
* Prepositions show the relationship between a noun or pronoun and other words in a sentence. They typically indicate location, time, or direction. For example: "The book is on the table."
* Adverbs modify verbs, adjectives, or other adverbs. They describe how, when, where, or to what extent something happens. For example: "He walked slowly."
"Even" modifies the words around it to indicate something is surprising or unexpected. For example:
* "Even the children were quiet." (Even is modifying "children" to emphasize the unexpectedness.)
