。
She went to the market to buy fresh vegetables.
Literal
She [topic-は] fresh vegetables [object-を] buying [to-に] market [to-へ] went.
Uses the purpose-of-motion construction [verb stem]+に+行く: 買いに行く ('go to buy'). 新鮮な (しんせんな, 'fresh') modifies 野菜 ('vegetables'), and 市場 (いちば/しじょう, 'market') is the destination marked by the directional particle へ. This sentence has a clean, practical feel — a simple errand described efficiently.
