The past tense of forbid is forbade, and its past participle is forbidden. Here's the thing — while the simple answer seems straightforward, the verb’s history, irregular conjugation, common usage pitfalls, and nuanced alternatives reveal a richer linguistic landscape that many speakers overlook. This article explores the forms, meanings, and contexts of “forbid” and its past tense, providing clear rules, examples, and answers to frequent questions so you can use the word confidently in both written and spoken English.
Introduction: Why the Past Tense of “Forbid” Matters
Understanding the correct past tense of a verb is essential for clear communication, especially in academic writing, storytelling, and formal correspondence. Forbid is an irregular verb, which means its past forms do not follow the regular “‑ed” pattern that most English verbs use. Mistaking “forbade” for “forbidden” (or vice‑versa) can change the grammatical role of the word and lead to awkward sentences. By mastering the proper conjugation, you’ll avoid common errors such as “He has forbade the rule” instead of “He has forbidden the rule,” and you’ll improve both precision and credibility in your language.
The Core Conjugation of “Forbid”

| he / she / it | forbids | forbade | forbidden |
- Simple Past (forbade) – Used for a completed action in the past.
- Past Participle (forbidden) – Used with auxiliary verbs (have, had, will have) to form perfect tenses or passive constructions.

Historical Background: From Old English to Modern Usage
The verb forbid originates from Old English forbiddan, a compound of the prefix for- (meaning “against”) and biddan (“to ask, command”). Which means in Middle English, the past tense appeared as forbade and forbode, reflecting the Germanic pattern of vowel change (ablaut) that characterizes many strong verbs, such as sing/sang/sung or drive/drove/driven. Over time, the past participle settled on the form forbidden, preserving the “‑en” ending typical of strong verbs.
Understanding this etymology clarifies why forbid does not simply add “‑ed.” It belongs to the same family as bind (bound, bound), find (found, found), and mind (minded, minded), where the vowel shift signals past tense.
When to Use “Forbade” vs. “Forbidden”
1. Simple Past Actions (forbade)
Use forbade when you describe a specific, completed act of prohibition in the past. The focus is on the act of forbidding, not the ongoing state.
- The mayor forbade street vendors from operating after 6 p.m.
- She forbade any further discussion of the topic.
2. Perfect Tenses and Passive Voice (forbidden)
Use forbidden when the prohibition is part of a perfect construction (has/had/will have), or when the verb functions as an adjective describing something that is not allowed.
- The book has been forbidden in several countries.
- It is forbidden to smoke in this building.
- They had forbidden the use of plastic bags long before the law changed.
3. Common Mistakes to Avoid
| Incorrect | Correct | Reason |
|---|---|---|
| *He has forbade the rule.That said, * | *He has forbidden the rule. * | “Has” requires the past participle. So |
| *The manager forbade the new policy. Practically speaking, * (when meaning the policy is still in effect) | *The manager has forbidden the new policy. * | Present perfect indicates ongoing relevance. Even so, |
| *It’s forbidden to forbid the children. Also, * | *It’s forbidden to forbid the children. * | “Forbidden” acts as an adjective; “forbid” remains a verb. |
