Grammar · です and negatives

です, the polite to be

The pattern

[Noun / na-adjective] desu

です is how you politely say is, am or are. It does not conjugate for person or number, so one form covers everything.

The mistake to avoid

です is pronounced closer to 'des'. The u is devoiced and almost disappears.

Examples

tanaka-san desu.

genki desu.
I'm well.
kore wa pen desu.
This is a pen.
watashi wa hatachi desu.
I am twenty.
