Final answer:
Understanding active and passive voice in linguistics is crucial for sentence structure and subject-object relationships.
Explanation:
Active and passive voice are two essential concepts in linguistics that determine the structure of a sentence and the role of the subject and object within it. In active voice, the subject performs the action, while in passive voice, the subject receives the action. For example, in the sentence, 'The patient was diagnosed with alopecia,' the verb 'diagnosed' is in the passive voice because the patient is receiving the action of being diagnosed.
