The past participle of 'write' is:

**The reasoning** English verbs have three main forms: **base form** (write), **past tense** (wrote), and **past participle** (written). The past participle is used with helping verbs like "have," "has," or "had." For example: "I have **written** a letter." "Write" is an **irregular verb**, meaning it doesn't follow the regular "-ed" pattern. You must memorize its forms: write → wrote → written. **Why the wrong options tempt you** **A) wrote** — This is the simple past tense ("I wrote yesterday"), not the past participle. Many students confuse these two because they both talk about past actions. **B) writed** — This looks like you're applying the regular verb rule (walk → walked), but "write" is irregular, so adding "-ed" creates a non-existent word. **D) writing** — This is the present participle/gerund form, used for continuous tenses ("I am writing") or as a noun. **Quick takeaway** Think of the phrase "have + past participle" — you say "I have **written**," never "I have wrote" — and remember: irregular verbs must be memorized, not guessed from patterns!
