To determine whether "in" is a linking verb, we first need to understand what a linking verb is. Linking verbs are verbs that connect the subject of a sentence to a complement, which can be a noun, pronoun, or adjective that describes or renames the subject. They do not show action but rather express a state of being.

Examples of common linking verbs include "be," "become," "seem," "appear," and "feel." These verbs are often used to describe a condition or state of being.

Now, let's consider the verb "in." "In" is typically a preposition and is used to indicate location or position within something. For example, in the sentence "The book is in the bag," "in" is a preposition showing the location of the book.

Importantly, "in" does not function as a linking verb because it does not connect the subject to a complement that describes or renames it. It simply indicates location or position.

In conclusion, "in" is not a linking verb, but rather a preposition.
