fungus (English)

Where does "fungus" come from?

The English word 'fungus' comes directly from the Latin 'fungus', which was used to refer to a 'mushroom'[1]. This Latin term likely originated from a non-Indo-European substrate language, as evidenced by its historical connection to the Ancient Greek word 'spongos' meaning 'sponge' and the Old Armenian 'sunkn'[2]. The word's earlier form, reconstructed as '*sfungus', highlights its deep historical ties to other ancient Mediterranean and regional terms for porous or mushroom-like growths[2].
