Etymology

The word "think" originates from Old English þencan, meaning "to seem, to appear, or to conceive in the mind." It is related to the Old High German denken and Dutch denken, all stemming from the Proto-Germanic þankijaną, which carries the sense of mental perception or reasoning. Over time, the meaning evolved from a general sense of appearing or seeming to the more specific cognitive act of reasoning or forming thoughts.
