impression
💭 noción = no + shun: you have NO 'shun' of the full details, just a notion
Spanish noción comes from Latin notio, from noscere 'to know', and is a close cousin of English notion. It means a basic idea or a vague grasp of something, as in 'tengo una noción de física'. Sounds like 'no-see-ON'.
