Past verbs are used to make past simple sentences
eg ran past tense of run: The dog ran to school.
or walked past tense of walk: We walked to school last week.
Past participles are used to make:
perfect verb phrases eg - has walked - have waited- had come
passive verb phrases eg - is played - are drunk - were eaten
Past participles for regular verbs are the same as the past simple
eg walk / walked / walked - just add -ed to the verb
for irregular verbs the past participle is a new word or sometimes the same word is used.
eg cut / cut / cut - for the verb cut all forms are the same.
or run / ran / run - the basic verb and the past participle are the same
or eat / ate / eaten - each form has a different word
