What does 컸 mean in Korean?

It is part of the past form of 크다.

크다 means “to be big” or “to grow.” 컸다 is its plain past form; 컸어 is the informal past form. By itself, 컸 is usually an unfinished word fragment, so the sentence supplies whether it means “was big,” “grew,” or “grew up.”

Why does 컸 look like one character?

It is a syllable block made from three jamo.

Hangul arranges jamo—consonant and vowel letters—into syllable blocks. Here, ㅋ is the initial consonant, ㅓ the vowel, and ㅆ the final consonant. Unicode normalization can represent the same text as one precomposed syllable or as its jamo sequence; the two forms are canonically equivalent.

The dates 1443 and 1446 mark Hangul’s development and promulgation, respectively; the script helped address the difficulty of writing Korean with Chinese characters.
