She's a typist.
Literal
She [topic-は] typist is.
The simplest noun-predicate sentence: [topic]+は+[noun]+です. This is the entry-level scaffold every learner meets in week one — 私は学生です ('I'm a student'), 田中さんは医者です ('Tanaka is a doctor'). The polite copula です sits at the end. As a stand-alone identification of occupation, the sentence has a CV-line feel — short, factual, polite. Note that occupational nouns in Japanese don't require an article (no 'a' / 'the' equivalent), so the sentence reads as 'she is typist' if translated word-for-word.
