Understanding Past Participles

• Past participles are a form of verb
• They often indicate completed actions

Formation of Past Participles

• Regular verbs create the past participle by adding "-ed" or "-d" to the base form.
• Irregular verbs have varied past participle forms that must be memorized.
• Regular past participle examples: "walked," "played," and "agreed."
• Irregular past participle examples: "gone," "seen," and "eaten."

Use as Adjectives

• Past participles can serve as adjectives, modifying nouns.
• They describe a noun's state as the result of a completed action.
• "broken window" exemplifies this, where "broken" modifies "window."
• "used car" shows "used" modifying "car."

Use in Perfect Tenses

• Past participles are needed to form perfect tenses.
• The present perfect tense is "have/has + past participle," as in "I have eaten."
• The past perfect tense is "had + past participle," as in "I had finished."
• The future perfect tense is "will have + past participle," as in "I will have left."

Use in Passive Voice

• Past participles are essential for forming the passive voice.
• The passive voice structure is "be + past participle," for example, "The book was written."
• This indicates the subject receives the action.

Examples in Sentences

• "The baked cookies smelled delicious" uses "baked" as an adjective.
• "She has traveled to many countries" uses the present perfect tense.
• "They had already left when I arrived" uses the past perfect tense.
• "The letter was delivered this morning" uses the passive voice.
