Hangul Syllable Ssan

Press Shift+T, K, then S on Dubeolsik.

Switch the input method to Korean first. Shift+T selects ㅆ, K selects ㅏ, and S supplies final ㄴ; the IME assembles them into 싼 as you type. On a Korean phone keyboard, tap ㅆ, ㅏ, then ㄴ in order.

If a program shows the parts separately, it is displaying the canonical jamo sequence rather than changing the reading; Unicode can compose and decompose Hangul syllable blocks during normalization.

what does 싼 mean in Korean

It means “cheap” before a noun.

싼 is the present noun-modifying form of 싸다 in its price sense: 싼 가격 and 싼 값 describe something priced low. It is Korean grammar, not a universal reaction you can read from the glyph alone.

This block's history is older than computing. The related adjective 싸다 is recorded in 1447 as Middle Korean for “to be worth”; modern Korean also keeps a separate “deserving” use in phrases such as 맞아도 싸다. Hangul was created to make Korean writable for people who lacked an accessible writing system and documented in 1446 with rules for combining initial, medial, and final sounds. ㅆ belongs to the doubled ㅅ family; ㄴ is the final consonant.
