Read these sentences. Can you see the pattern?
- She built a sandcastle at the beach yesterday.
- They built a new house last year.

Did you notice? Every time we talk about the past, the word is built — not “build” and not “builded.”
| Form | Word | Example |
|---|---|---|
| Present | build | I build things every day. |
| Past | built | I built a table yesterday. |
| With have/has/had | built | I have built many things. |
Why It Is “Built” and Not “Builded”
Most verbs in English add -ed to make the past tense:
- play → played
- walk → walked
- clean → cleaned
But build is different. It is an irregular verb. Instead of adding -ed, the “d” at the end changes to a “t”:
- build → built
The good news? The past form and the “with have/has/had” form are the same — both are built. You only need to remember one word.
Easy way to remember: Think of the word spend. You say “I spent money” — not “I spended money.” The “d” changes to a “t,” just like build → built.
The Rule in One Line: Build → built. The “d” becomes a “t.” Past and participle are both built.
Real-Life Examples With Build and Built
Here are sentences you might hear or use in everyday life:
- My grandpa built this house in 1985. (= He made the house a long time ago.)
- The children built a fort out of boxes. (= They made a play house from cardboard boxes.)
- She has built a great team at work. (= She created a strong group of people.)
- They built the bridge in just six months. (= They made the bridge quickly.)
- We are building a new school in town. (= The work is happening now — use “building” for right now.)
You are doing great. Now let us look at the mistakes many learners make.
Two Mistakes to Avoid With Build
Even advanced learners mix up “build” and “built” sometimes — so if you get confused, you are not alone. Here are the two most common mistakes:
Mistake 1: Adding -ed
✗ They builded a new park.
✓ They built a new park.
✗ She has builded three websites.
✓ She has built three websites.
Mistake 2: Using “build” for the past
✗ We build this last summer.
✓ We built this last summer.
How to remember: Look at the ending. In the past, the “d” becomes a “t.” Say it out loud: “buil-t.” You can hear the difference. The “t” sound tells you it is past tense.
Other verbs that work the same way: spend → spent, send → sent, bend → bent, lend → lent. They all change “d” to “t” in the past.

Keep Going — You Are Building Something
You just learned that build becomes built in the past. That is one more irregular verb you will never get wrong again.
But here is something interesting. What happens when a verb ends in a “tch” sound? For example, do you know the past tense of catch? Is it “catched” or “caught”? The answer might surprise you — because the spelling changes in a very different way.
