Morphology

vitamin + D

The phrase is a straightforward subtype label formed from 'vitamin' plus the conventional letter name 'D', so a B1 learner who knows 'vitamin' and alphabetic labels will understand it denotes a specific vitamin. While the exact biochemical roles are specialist information, the basic meaning 'a vitamin called D' is compositionally transparent and cross-linguistically regular.

Etymology

Vitamin D got its name when early scientists were finding things they called 'vitamins' and used letters to tell them apart, so this one became 'D'. It was the one linked to sunlight and to preventing the bone disease rickets, so today vitamin D is the vitamin our skin makes in the sun that helps keep bones and teeth strong.
