。
She is very pretty.
Literal
She [topic-は] very pretty.
きれい is famously a na-adjective even though it ends in い — a perennial trap for learners. The kanji form 綺麗 makes the trap less visible; in hiragana it looks i-adjective-shaped but conjugates as a na-adjective (きれいだ, きれいな人, きれいに). It covers both 'pretty' (of people) and 'clean' (of objects/spaces) — context disambiguates.
