ρεύμα
Lemma: ρεύμα
Translation: current; flow; electricity; stream (noun)
Etymology: From Ancient Greek ῥεῦμα (rheuma), derived from ῥέω (rheō) meaning 'to flow'. The same root gives us English words like 'rheumatism' (originally referring to bodily fluids flowing), 'rhythm' (flowing movement), and 'diarrhea' (flowing through). The semantic extension to 'electrical current' mirrors the development in other European languages, conceptualizing electricity as a flowing force.
Mnemonics
- Think of 'rheumatism' - both involve flow (of electricity or bodily fluids)
