Hangul Syllable Syeoss

It joins 시, which honors the subject, with past 었.

So 셨 contributes both subject respect and past time, but no action of its own. In 가셨어요, 가 means “go,” while the final 어요 sets everyday politeness toward the listener. Read the whole verb to know what happened.

Why is 셨 in 수고하셨습니다?

It acknowledges completed effort and treats the worker respectfully.

As of 2026, 수고하셨습니다 is a formal post-task acknowledgment of someone's effort. The ending after 셨 sets speech level toward the listener: 오셨어 can be casual while still honoring the person who came, whereas 오셨습니다 is formal. Using subject honorification for your own first-person action is not the standard form; use a plain past form.

What does Hangul history tell us about 셨?

It belongs to a writing system created for Korean.

Hangul's development was completed in 1443; its design was explained in the 1446 book 훈민정음. The writing system was designed for Korean sounds and grammar and to widen access to writing. Modern Korean spelling follows a 1933 unified-spelling proposal. Those dates concern the script and spelling standard, not the first recorded use of this exact syllable.
