Journey

Notion entered English through learned and literary channels after the Norman period, when many abstract Latin terms arrived via French. Its history shows a common pattern: a word for ‘knowing’ in Latin becomes an abstract term for an idea or concept in English.

Evolution

  1. Latin

    notiō

    “act of becoming acquainted with; conception, idea”

    Built from nōscere ‘to know’ with the -tiō noun ending.

  2. Old French

    notion

    “idea, understanding”

    Borrowed from Latin with a largely intellectual sense.

  3. Middle English

    notion

    “idea, opinion, whim; later also small article of trade”

    The sense ‘small practical article’ is an older English development, now archaic or dialectal.

  4. Modern English

    notion

    “idea; concept; impression”

    Most common current uses are abstract.
