Core Pattern Rule: Comparing with -만 하다
The pattern -만 하다 is used to compare the size, amount, or degree of one thing to another. It's equivalent to saying "is as big as," "is the size of," or "is as much as" in English.
Formation
Attach -만 하다 directly to a noun. The noun serves as the standard of comparison.
Noun + -만 하다
For example, 주먹 (fist) + -만 하다 becomes 주먹만 하다 (to be the size of a fist).
Usage
This pattern is very common in everyday speech for making vivid comparisons, often with a degree of exaggeration. It's a descriptive predicate, meaning it acts as the verb of the sentence.
얼굴이 주먹만 해. / 집이 궁전만 해요. / 해결해야 할 문제가 산만 해.
Idiomatic Expressions & Exaggeration
A key feature of -만 하다 is its frequent use in fixed, idiomatic expressions. These phrases often use exaggeration to make a point and their literal meaning might not be obvious.
Here are some common examples from the script:
얼굴이 주먹만 하다: To have a very small face (considered a compliment in Korea).
월급이 쥐꼬리만 하다: Lit. "Salary is the size of a mouse's tail." Means to have a very small salary or earn peanuts.
간이 콩알만 해지다: Lit. "Liver becomes the size of a bean." Means to be scared stiff or for one's heart to sink.
목소리가 기차 화통만 하다: Lit. "Voice is as big as a train whistle." Means to have a very loud, booming voice.

Synonyms & Differences: -만 하다 vs. -처럼/-같이
While -만 하다 is used for comparisons, so are particles like -처럼 and -같이 (like, as). However, they function differently.
-만 하다
Function: Acts as the main predicate (verb) of the sentence.
Focus: Specifically compares size, amount, or degree.
Example: 집이 궁전만 해요. (The house is as big as a palace.) Here, -만 해요 is the verb.
-처럼 / -같이
Function: A particle attached to a noun. It requires a separate verb to complete the sentence.
Focus: A more general comparison of similarity.
Example: 집이 궁전처럼 커요. (The house is big like a palace.) Here, 처럼 modifies 궁전, and 커요 is the main verb.
Both sentences convey a similar idea, but -만 하다 packages the comparison and the verb into one neat expression.
집이 궁전만 해요. / 방이 운동장만 해. / 저 사람은 모델처럼 키가 커요.
Politeness & Formality
The politeness level of -만 하다 is adjusted by conjugating the verb 하다. The script provides clear examples of both casual and polite forms.
Casual Speech (반말)
For friends, family, or those younger than you, 하다 conjugates to 해.
-만 해
-만 해졌어 (past tense, for a change of state)
Polite Speech (해요체)
In standard polite situations, 하다 conjugates to 해요.
-만 해요
-만 해졌어요 (past tense)
Notice how 내 손바닥 (my palm) in the casual sentence becomes 제 손바닥 in the polite version, reflecting a change in pronouns as well.
강아지가 내 손바닥만 해. / 강아지가 제 손바닥만 해요. / 간이 콩알만 해졌어. / 간이 콩알만 해졌어요.
