Answer:Yes, "an" is a linking verb.While it might seem unusual, "an" is considered a contraction of "am" and "one." In the sentence "I am an engineer," "an" is a linking verb connecting the subject "I" with the predicate nominative "engineer." It indicates the subject's identity or state of being.It's important to note that this usage is less common and might be considered informal in some contexts.
