Morphology
vitamin + K1
The compound follows a transparent naming pattern: 'vitamin' plus an alphanumeric label indicates a specific subtype (as in vitamin A, vitamin C), so a learner who knows 'vitamin' and recognizes 'K1' as a label can infer it is a particular form of vitamin K. While biochemical details (phylloquinone, fat-soluble properties) are not derivable, the basic sense 'a kind of vitamin K' is compositionally obvious to B1 learners.
Etymology
Vitamin K1 may come from the letter K, chosen by early scientists from a German word for 'clotting', and the number 1 marks the plant form found in green leaves. So imagine a green leaf with 'K1' on it to remember that vitamin K1 helps 'blood clotting' and keeps bones healthy.
