molécula
/moˈlekula/ · B2 · noun · f
molecule
🧪 molécula = mole (unit of amount) + -cula (tiny) → a tiny bit of matter
Spanish molécula comes from Latin moles, meaning mass, plus the diminutive -cula, meaning little. So it literally means little mass. Same ending as in English molecule, so the sound carries over almost unchanged.
