FAQ
What is verb conjugation in English?
Verb conjugation is the process of changing a verb's form to indicate tense, person, or number. In English, verbs conjugate for third person singular present (adds -s/-es), past tense (adds -ed or changes form), and present participle (adds -ing).
What is the past tense?
The past tense is a verb form used to describe actions or states that happened in the past. Regular verbs form the past tense by adding -ed (e.g., walked, played), while irregular verbs have unique past forms (e.g., go → went, buy → bought). The past tense can be used independently as the main verb, such as "I walked to school yesterday."
What is the past participle?
The past participle is the third principal form of a verb. For regular verbs, the past participle is the same as the past tense (e.g., walked), but irregular verbs may differ (e.g., go → went → gone). The past participle cannot stand alone as the main verb—it must be used with auxiliary verbs: in perfect tenses (have/has + past participle, e.g., "I have eaten") and passive voice (be + past participle, e.g., "The book was written").
What is the difference between past tense and past participle?
The past tense can function independently as the main verb in a sentence (e.g., "She wrote a letter"), while the past participle must be used with auxiliary verbs. The past participle is used in perfect tenses ("She has written three letters") and passive voice ("The letter was written by her"). For regular verbs, both forms are identical (both add -ed), but irregular verbs often differ, such as write → wrote (past tense) → written (past participle).
