Frequentemente confundido com

です vs だ (da)

Both mean 'to be,' but 'da' is the informal/plain version, while 'desu' is the polite version.

です vs ます (masu)

Both make a sentence polite, but 'desu' follows nouns and adjectives, while 'masu' follows verbs.

📝

Notas de uso

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.

⚠️

Erros comuns

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.
