Bone vocabulary is not memorized, it is assembled. Pick a prefix, one or two skeletal roots and a suffix, and the forge shows you the finished term, whether the combining vowel survived, and exactly why. Work the ten challenges at the top of the right panel — each one names a meaning and asks you to build the word that carries it.
1 · Prefix (optional)
2 · Root
3 · Second root (optional — builds oste·o·myel·itis)
4 · Suffix
Challenge 1 of 10
