The past participle of choose is "chosen." It forms the perfect tenses (e.g., "I have chosen") and passive constructions (e.g., "She was chosen for the team"). It is an irregular verb form that does not follow the standard -ed pattern.
Chosen appears in completed actions involving selection. It pairs with auxiliary verbs like "have," "had," or "be" to express time, completion, or passive voice. For example, "They have chosen their finalists" shows a decision made in the past with relevance to the present.
Unlike regular verbs such as "walked" or "played," which add -ed to form the past participle, "choose" changes its spelling entirely. The base form is "choose," the past tense is "chose," and the past participle is "chosen." This triad is consistent across all English dialects and is standardized in grammar references.
Chosen always follows an auxiliary verb. In active perfect tenses, it comes after "have" or "had." In passive voice, it follows "was," "were," or "has been."
Examples:
These structures emphasize completion or result. "Has chosen" implies the action is finished and affects the current state. "Was chosen" shifts focus to the subject receiving the action, not performing it.
Using "chosen" correctly avoids common errors. Do not say "I have chose" or "She had choose." These violate subject-verb agreement and tense consistency. The correct form is always "chosen" after auxiliary verbs.
Verbs like "choose" belong to a group of irregular verbs that change their root vowel or add internal letters in past forms. Others in this category include "break/broke/broken," "take/took/taken," and "write/wrote/written."
| Base Verb | Past Tense | Past Participle |
|---|---|---|
| choose | chose | chosen |
| take | took | taken |
| write | wrote | written |
| bring | brought | brought |
Notice that "bring" has the same past and past participle form. This is rare among irregular verbs. Most, like "choose," differ between past tense and past participle.
Some verbs share patterns. "Choose" and "lose" both drop the -e and add -en in the past participle. "Lose" becomes "lost," not "loosen." But "choose" becomes "chosen" - a unique transformation not shared with other verbs.
Many learners assume "chosen" ends in -ed because it sounds like a regular verb. But it does not. Saying "I have choosed" or "She had choosed" is incorrect. The past participle must be memorized as a unit.
Another error is using "chosen" in simple past tense. "She chosen the winner" is ungrammatical. The correct form is "She chose the winner." The past participle cannot stand alone without an auxiliary verb.
Confusion often arises in passive constructions. "The award was choosing" is wrong. It must be "The award was chosen." The past participle is required in passive voice, never the past tense.
Consider this sentence: "After reviewing 200 applications, the committee has chosen five candidates." Here, "has chosen" indicates a completed action with ongoing relevance. The selection process is done, and the results matter now.
In news reporting: "The new mayor was chosen in a landslide vote." The passive construction highlights the outcome, not who performed the act. The focus is on the person selected.
Personal narrative: "I've chosen to study abroad next year." This uses the present perfect to show a decision made in the past with future implications. The choice affects current plans.
As a test, try replacing "chosen" with "selected" in these contexts. They are interchangeable in most cases. "Selected" is more formal and less common in spoken English. But both are correct past participles for "choose."
I once corrected a student's essay where they wrote, "The teacher had choose the book." After pointing out the missing -n, they paused and said, "But it sounds like 'chose' with an -ed." That moment revealed a deeper issue: phonetic similarity doesn't imply spelling rules. "Chosen" is not derived from "chose" plus -ed - it's a separate morpheme.
This misunderstanding persists even among advanced learners. The brain hears "chose" and assumes the past participle should follow the same pattern. But English irregularity defies logic. Memorization and exposure are key.
The Oxford English Dictionary confirms that "chosen" has been used since Middle English (c. 1300) as the past participle of "choose." It notes that the form evolved from Old English "ċēosan" (to select), with the past participle appearing as "ġecōsen" in early texts.
According to the Cambridge Grammar of English, "chosen" is used exclusively with auxiliary verbs in perfect and passive constructions. It states that "the past participle of irregular verbs must be learned individually, as no rule predicts them."
Both sources agree: "chosen" is not optional. It is the only correct form in all standard English varieties, including American, British, and Australian English.
See how "drink" forms its past participle - another irregular verb with a distinct pattern. "Drank" is the past tense; "drunk" is the past participle. No -ed. No logic. Just memorization.
Understanding the past participle of choose is essential for accurate writing and speaking. It enables clarity in expressing completed actions, decisions, and passive events. Without it, communication falters.
Mastering "chosen" means recognizing it as a fixed form, not a pattern. It is not "chose" plus -ed. It is not "choose" with a suffix. It is a standalone word with a long history and strict rules. Use it correctly, and your English will sound natural and precise.
