Active and passive words refer to the way verbs are used in a sentence.
Active words are used when the subject of the sentence performs the action of the verb. For example, in the sentence "She ate the apple," the subject "she" is performing the action "ate."
Passive words, on the other hand, are used when the subject of the sentence receives the action of the verb. For example, in the sentence "The apple was eaten by her," the subject "the apple" is receiving the action "was eaten."
