Past tense and past participle of Light?

Answer 1

The technically correct answer to your question is "lighted."

The past participle form for regular verbs are the same thing as past tense. Light is technically a regular verb, so therefore you would use a past participle form (adding ed, d, t,) to the base form to come up with the past participle (past tense).

However, English is a living language and relational words (nouns, adverbs, adjectives, verbs) have the ability to change form and meaning over time due to popular acceptance, culture, etc. so another acceptable and commonly used form for the past tense of light is "lit." The ability to use both lighted and lit correctly essentially makes the verb "light" both a regular and irregular verb at the same time.

Answer 2

The past tense of "light" is "lit" or "lighted." The past participle is also "lit" or "lighted."
