How It's Used
Chemistry
"Electrons flow from the cathode to the anode in a galvanic cell."
Physics
"The anode attracts negatively charged particles."
From Greek ἄνοδος (ánodos), from ἀνά (aná, "up") + ὁδός (hodós, "way"), literally "the way up". Named because in electrolysis, positive ions move toward it.
The term's usage aligns with the development of electrochemistry in the 19th century.
Memory tip
