What does 发现 mean?
发现 (fāxiàn) means 'to discover, find out, or notice' — to become aware of something that was previously unknown or hidden. Literally 发 ('to send out / cause to appear') + 现 ('to appear'), it covers a wide range: scientific discoveries (科学家发现了新行星 'scientists discovered a new planet'), personal realizations (我发现自己错了 'I realized I was wrong'), and noticing something (我发现钱包不见了 'I noticed my wallet was gone'). Two distinctions matter for English speakers.
First, 发现 is about awareness, not physical retrieval — to 'find' a lost key on the floor and pick it up is 找到 (zhǎodào), while to 'find out' or 'notice' it is 发现. Second, 发现 doubles as a noun meaning 'discovery / finding' (一个重要的发现 'an important discovery'), without changing form.

Memory hook: 发 ('cause to') + 现 ('appear') — to discover is to cause something hidden to appear in your awareness.
