'Matchida' or 'matchuda'? A Korean grammar lesson wrapped in a stock market chat

Clearing up the confusion between "matchida" and "matchuda"

Cheolsu: SK Hynix closed up 12.73 percent on Wednesday after announcing a large-scale share buyback and cancellation plan.

Younghee: Samsung Electronics has also unveiled a shareholder return plan, and expectations are growing that the Korean stock market has bottomed out and is set to rise again. Can you guess (matchida) whether Samsung Electronics and SK Hynix shares will climb again today?

Cheolsu and Younghee are discussing the share price outlook for Samsung Electronics and SK Hynix.

In their exchange, Younghee's use of "matchuda" should be replaced with "matchida" — and here is why.

"Matchida" (맞히다) is used when finding the correct answer or hitting a target precisely. Examples include: "Can you guess the answer to the question?" "I got a rabies shot" and "An arrow that hit the bull's-eye exactly."

"Matchuda" (맞추다), by contrast, is used when comparing or adjusting two or more things under similar conditions. It appears in expressions such as "The clothes fit as if they were tailored," "Let's keep pace with the other department," and "You put the pieces together well."

The two words are frequently confused because they share the same stem — the verb "matda" (맞다), which carries multiple meanings including "to be correct" and "to match." "Matchida," formed with the causative suffix "-hi," is used when accurately identifying an answer or hitting a target. "Matchuda," formed with the transitive suffix "-chu," is used when adjusting something to achieve alignment.

A tip for Korean language lovers: use "matchida" for correctness and precision, "matchuda" for comparison and adjustment.
