The past tense of lead is led — three letters, no a: "He led the negotiations last year." Lead is only the present tense ("she leads the department") or a noun (the metal, a leash, first place). If the action already happened, it is always led.
Why this one catches everybody
English has a trap here that no other verb quite matches. The metal lead — the heavy grey one in old pipes — is pronounced exactly like led. So the spelling l-e-a-d is genuinely attached to the sound "led" somewhere in your memory, and the hand reaches for it when you write a past tense.
Compare it with read, where present and past really are spelled the same: I read the report yesterday. Lead does not work that way. Its past tense has its own spelling.
The forms
- Present: lead (rhymes with need) — I lead a small team. They lead the market.
- Third person: leads — She leads the Friday session.
- Past and past participle: led — He led the walk. She has led four expeditions.
- -ing form: leading.
The test
Ask whether the action is finished. If it is, spell it led — no exceptions, no edge cases. A second check: swap in another irregular verb like ran. If ran fits, you need led: "he ran the meeting" / "he led the meeting". If run fits, you need lead: "he can run the meeting" / "he can lead the meeting".
The auxiliary rule catches the rest: after has, have, had, was or were, it is always led — the inquiry was led by a retired judge.
Lead as a noun
Several separate nouns share the spelling, and none of them is a past tense:
- The metal, pronounced "led": lead piping, lead paint, leaded windows.
- First place: Norway took the lead in the final lap.
- A dog's leash: Keep him on the lead near the road.
- A clue: The police are following up a new lead.
- The main role or performer: She played the lead.
- A sales prospect: The campaign generated forty leads.
Be honest about how common the error is
"Lead" used as a past tense turns up constantly, including in professionally edited copy — CVs and LinkedIn profiles are especially thick with "lead a team of twelve". A spellchecker will never flag it, because lead is a real word. It is worth a targeted search before you send anything where the wording matters.
Misled, not mislead
The same trap catches the compound: the past of mislead is misled. The advert misled customers — not "mislead".
Frequently Asked Questions
Is it "I lead the project last year" or "I led the project last year"?
I led the project last year. This is the single most common version of the error, and it shows up constantly on CVs. Any completed action takes led.
Why is "lead" sometimes pronounced like "led"?
Because the noun for the metal is spelled lead but rhymes with bed, while the verb lead rhymes with need. Two different words that happen to share a spelling.
What's the past tense of mislead?
Misled. It follows lead exactly: "The figures misled investors." Writing "mislead" for a past action is the same mistake one step along.
