Learning Spanish & Etymology Pattern-Matching for Nerds

The Spanish brazo (“arm”) comes from the Latin bracchium meaning, “upper arm.” The Latin itself comes from the Greek brakhion. From these, we get English words such as bra (more recognizable if we remember the older, and original French, form of the word, brassière) as well as bracelet

We can see the br‑c and its variations (br‑z, br‑s) in all the versions of the word.
