Jeringa, Spanish for Syringe, sounds like it has nothing in common with its English counter-part. But they are literally the same word.

The Latin sh- sound often evolved into the j- sound in Spanish — originally retaining the sh- sound but eventually, under Arabic’s influence, transforming to the throat-clearing sound we know and love.

This explains how both jeringa and syringe derive from the same root: the Latin siringa, itself from the Greek syringa. The sy- sound is a variation of the sh- sound and therefore the sy-r-n‑g of syringe maps to the j‑r-n‑g of jeringa.
