The drawing: Drawn for this site, 2026-09-20. Proportions and bone shapes were checked by eye against three public-domain pictures on Wikimedia Commons: Gray188.png (side view of the skull from Gray, Anatomy of the Human Body, 1918), Human_skeleton_front_-_no_labels.svg and Human_skeleton_back_en.svg (Mariana Ruiz Villarreal, released into the public domain), and against the descriptions of the wrist and ankle bones in the English Wikipedia articles Carpal bones and Tarsus (skeleton). Nothing was traced or copied, and the numbers and labels are our own. Licence: own work
How it works
Thirty-five bones of the skeleton are named in French here, from l'os frontal on the skull to les phalanges du pied. Twenty-five names are masculine and ten feminine.
Read the full guide
Two names for one bone
For six of these bones French has an everyday name and a newer anatomical one, such as l'omoplate and la scapula for the shoulder blade. The drawing shows the everyday name, the one WordReference and Larousse use, and the newer name counts when typed.
What l' hides
L' does not show the gender. L'os, l'humérus, l'ilion, l'ischion and l'astragale are masculine; l'omoplate is feminine.
A whole hip bone is l'os iliaque. L'ilion, le pubis and l'ischion are its three parts.
Questions and answers
How do you say skeleton in French?
Le squelette, masculine. The skull is le crâne, the spine la colonne vertébrale, and one bone is un os.
How do you pronounce os in French?
In the singular the s is heard: Larousse says un os sounds like the French word cosse. In the plural the s is silent, and des os sounds like eau. WordReference notes the plural too.
What are the bones of the body in French?
Among the best known: le crâne (skull), la clavicule (collarbone), les côtes (ribs), l'humérus, le radius, le fémur, la rotule (kneecap) and le tibia. The English name stands beside every French one in the list under the drawing.
Is tibia masculine or feminine in French?
Masculine: le tibia, un tibia, in WordReference and Le Robert. Spanish and Italian make the same bone feminine, la tibia.
Where were the French names checked?
In WordReference, Le Robert and Larousse, and for the anatomical names in the medical dictionary of the Académie nationale de médecine. Each name stands in at least two of the four.
