What Does 커지다 Mean?

커지다 builds on the adjective 크다 and adds the meaning of change. The thing that grows takes 이/가, as in 소리가 커져요 or 문제가 커지다. It is very common with 점점 (gradually), and its opposite is 작아지다.

Because the word means "become big", it pairs with nouns that can grow: a sound getting louder, a worry, a company, a gap between people. The change usually happens without anyone choosing it, so 커지다 rarely appears with -고 싶다, and the table below leaves that form out.

How Do You Pronounce 커지다?

After ㅈ, the vowel ㅕ is said as a plain ㅓ, so 커져요 is read [커저요] and 커졌어요 [커저써요]. In the formal 커집니다, ㅂ becomes ㅁ before ㄴ: [커짐니다].

How Do You Use 커지다 in a Sentence?

Music growing louder, children growing taller and a worry growing larger.

음악 소리가 점점 커져요.

The music gets louder and louder.

소리가 is the subject with 가, and 점점 shows the change is gradual.

아이들의 키가 많이 커졌어요.

The children have grown a lot taller.

The past 커졌어요 reports growth that has already happened to 키.

문제가 커지면 저에게 말해 주세요.

If the problem gets bigger, please tell me.

The conditional 커지면 sets up a request: tell me when the problem grows.

How Does Keojida Conjugation Work?

The stem is 커지, built from 크 plus 지다. The ㅡ of 크 has already dropped inside it, so the rest is regular: the stem plus 어요 contracts to 커져요. The conditional 커지면 and the modifier 커지는 follow the same plain pattern.

Common Mistake

Wrong: ✗ 소리가 크져요

Correct: ✓ 소리가 커져요

Why: 커지다 is built from 크다 plus 지다. Learners keep the ㅡ of 크 and write 크져요, but the ㅡ drops before 어, giving 커, and only then is 지다 added: 커져요.

The Television Is Getting Louder

Two housemates are watching television. One notices a change in volume. The other compares it with a moment earlier, and the first predicts what the next scene will do.

Mina

소리가 점점 커져요.

Soriga jeomjeom keojyeoyo.

The sound is getting louder.

Alex

맞아요. 아까보다 커졌어요.

Majayo. Akkaboda keojyeosseoyo.

Yes. It has become louder than before.

Mina

다음 장면에서는 더 커질 거예요.

Daeum jangmyeoneseoneun deo keojil geoyeyo.

It will get even louder in the next scene.

Alex

그럼 소리를 줄여요.

Geureom sorireul juryeoyo.

Then let’s turn the sound down.

커져요 describes the developing change, 커졌어요 reports the difference already noticed, and 커질 거예요 predicts a further increase. The final line gives someone an action to take: 줄이다, “reduce”, acts on the sound.

What Commonly Gets Bigger?

소리가 커지다 means a sound gets louder. Korean describes volume with “big”, so this expression does not mean that a speaker or television becomes physically larger. With 목소리, “voice”, it can describe someone speaking more loudly during an argument or trying to be heard across a room.

문제가 커지다 means a problem grows more serious. The change may concern consequences, people involved or the work needed to solve it. The expression does not identify who caused the escalation. In a workplace conversation, the existing conditional example asks the listener to report the problem if that change happens.

차이가 커지다 means a difference grows. 차이 can concern prices, scores, opinions or ability. Adding 점점 presents a gradual widening; 더 presents a further increase. Neither word is required by 커지다, but each gives the learner a more precise way to describe the change.

기대가 커지다 means expectations grow, and 걱정이 커지다 means worry increases. These uses extend the size image to degree. Translate according to the noun: expectations “rise”, a worry “grows”, and a sound “gets louder”. Keeping “bigger” in every English translation can hide the natural meaning.

Where Will You Hear 커지다?

Everyday talk uses 커졌어요 when noticing a change since the last meeting: a child’s height, a plant’s size or the lettering on a screen. The past form often points to a present result. Something has become bigger, and the speaker can see the difference now.

News reports use 커지다 for concern, expectations and disagreements. Read the subject first. A headline about a growing worry is describing a change in feeling or public concern, rather than an object’s dimensions. The verb alone does not tell you whether the change is welcome.

In device instructions, 커지다 describes what happens to the display or sound. 키우다 describes a user making it larger or louder. This distinction helps when explaining a fault: you can report that the volume increased without saying you deliberately turned it up.

How Do You Keep the Changing Thing as the Subject?

Choose 커지다 when the sentence follows the thing that changes. The pattern is a noun plus 이/가 and 커지다. Choose 키우다 when you want to name someone who makes the change; then the enlarged thing takes 을/를. A natural sentence depends on that choice before you select the ending.

Compare the three ideas using 소리: 소리가 크다 describes loud sound; 소리가 커지다 describes sound becoming louder; 소리를 키우다 describes increasing the volume. The vocabulary is close, but the first is a state, the second a change and the third an action causing a change.

Write 커지다 as one word. Its present form 커져요 comes from the stem 커지, so the ㅡ-drop rule for 크다 does not need to be applied again. Keep 지 before consonant endings such as 커지면 and 커지는. Before 어-type endings, the familiar contracted forms are 커져요 and 커져서.

크다 to be big Describes the size or degree already present.
키우다 to raise / enlarge Someone causes growth or an increase.
작아지다 to become smaller The change goes in the opposite direction.
