    A keyword is a word you type into a computer so it will search for that word — on the internet, in a shop’s search box, or inside a file. If you type “night market ”, those are your keywords, and the computer tries to find pages that match them. Students, , and anyone looking things up use this word every day; it is normal English now, not only for experts. People stretch it, too: a short phrase often counts as a “keyword,” not only a single word. Though actually, the idea is older than Google. A keyword was already “the important word that tells you what a text is about,” and teachers still use it that way in class. (In computer code, keyword can also mean a special reserved word like if; that is a different job for the same label, and not the sense you need first.)
