Question

Which word is the linking verb when I taste something spicy, I fell uncomfortable

Answer 1

We can observe that the sentence structure of this statement is in passive form. The active form is the most easiest way and another method to identify linking verbs with ease. Hence, the sentence would be like:
1.      I felt uncomfortable when I taste something spicy.
Evidently, if we analyse the sentence structure in this form we can observe that “when” here is used as a linking verb. Linking verbs are connecting words that combine a subject and a predicate. Includes such as is, are, was, were and verbs.
