the unsung electrode that gives up its electrons so your devices can live
means the electrode through which conventional current enters a device — the positive terminal in something being charged, where oxidation happens and electrons depart.
from Coined in the 1830s by English polymath William Whewell at the request of Michael Faraday, who wanted clean Greek names for his electrical discoveries. It stitches together Greek 'ana-' (up) and 'hodos' (way, road) — literally 'the way up,' picturing the path the sun's current seemed to take rising in the east. Its partner 'cathode' is 'the way down.' That same 'hodos' walks quietly through words like 'exodus' (the way out) and 'method' (a way of pursuing).
