자주 혼동되는 단어
Both mean 'to be,' but 'da' is the informal/plain version, while 'desu' is the polite version.
Both make a sentence polite, but 'desu' follows nouns and adjectives, while 'masu' follows verbs.
사용 참고사항
Desu is placed at the very end of a sentence to complete the thought politely. It can follow a noun, a na-adjective (without the 'na'), or an i-adjective.
자주 하는 실수
Beginners often try to add 'desu' after a verb in its polite 'masu' form (e.g., 'tabemasu desu'), which is incorrect because 'masu' already contains the politeness and ending function.

어원
Commonly thought to be a contraction of 'de gozaimasu' or 'de arimasu,' standardizing during the Edo period as a polite copula.
