You use “study” all the time, right? Kids study at school. You study for tests. We all study stuff. Every single day.
Maybe you’re studying English now. Or math. Or for next week’s test.
But wait. What about yesterday? Last night? Last year? You need the past form. That’s when English verbs change. Good news though, study is super easy!
The past form of study is studied.
Yep, that’s it. Study becomes studied. This guide shows you how. You’ll learn when to use each one. You’ll see examples. Tables too. And mistakes to avoid. By the end? You’ll feel great using it!
Let’s go!
What Does Study Mean
Study means to learn stuff. Read things. Think hard. Remember facts. Practice skills. You do it to know more. Students study lessons. Workers learn new skills. Doctors learn medicine. Kids do homework.
Look at these:
- I study English.
- They study each night.
- She studies math.
- We study after class.
Study is a regular verb. Which means? It follows easy rules!
What Is the Past Form of Study
The past form? Studied.
The past participle? Also studied.
So easy!
Study → Studied
Study → Studied
Use studied when it’s done. Finished. Maybe yesterday. Last night. Years ago even.
Like this:
- I studied last night.
- She studied five hours.
- We studied at the library.
- They studied after school.
All past actions. So we use studied.
How to Make the Past Form of Study
Study ends with ‘y’. Most verbs with consonant + y? They change. The y becomes i. Then add ed.
Here’s how:
- Study
- Drop the y → stud
- Add ied → studied
Same thing happens here:
- Carry → carried
- Try → tried
- Cry → cried
- Apply → applied
See? Study follows this rule. That’s why it’s studied, not studyed.
