です

です is the polite copula used after nouns and na-adjectives to state something is the case. It marks the sentence as polite and neutral in tone. Use です in everyday conversations, introductions, and when speaking to strangers or officials. It is not used after verbs; instead you use the verb in its appropriate form. In questions, add か after です to ask nicely, and in negative statements, use ではありません or じゃありません in more casual settings.
