The adjective 'ostry' has three major meanings: 'sharp' (about a blade, e.g., 'ostry nóż' — sharp knife), 'spicy / hot' (about food, e.g., 'ostry sos' — spicy sauce), and 'severe / acute' (about pain, illness, weather, or critique, e.g., 'ostra zima' — severe winter, or 'ostry ból' — acute pain). Note: the source metadata mistakenly lists this as a noun, but it is an adjective. In the masculine personal plural, it becomes 'ostrzy'. Comparative is 'ostrzejszy', superlative is 'najostrzejszy'. The adverb is 'ostro' (sharply / spicy).
