Linking Verbs & No-Action Verbs

Linking verbs and non-action verbs are related but not exactly the same. Here's the breakdown:
Linking Verbs
 * Connect the subject to a word or phrase that renames or describes the subject.
 * Don't express action.
 * Common linking verbs include:
   * Forms of "to be" (am, is, are, was, were, be, being, been)
   * Become, seem, appear, feel, look, smell, taste, sound, grow, remain, prove, turn
Example:
 * The sky is blue. (Blue renames the sky.)
 * She feels happy. (Happy describes her feeling.)
Non-Action Verbs
 * A broader category that includes linking verbs and other verbs that don't express physical action.
 * Can express states of being, senses, emotions, or relationships.
 * Examples:
   * Have, own, possess (states of possession)
   * Know, believe, think (mental states)
   * Love, hate, like (emotions)
Key Difference:
 * All linking verbs are non-action verbs, but not all non-action verbs are linking verbs.
 * Non-action verbs can express a wider range of states and conditions beyond simply renaming or describing the subject.
In Summary:
Linking verbs are a specific type of non-action verb that connects the subject to a description or renaming word or phrase.
