ash
The powdery residue left after combustion; also, a tree of the genus Fraxinus.
Etymology
Modern English ash (the tree) comes from Old English æsc "ash tree, spear (made of ash wood)," from Proto-Germanic *askaz, possibly from PIE *h₃es- "ash tree." The word's dual meaning — tree and spear — reflects how central ash wood was to weapon-making in the Germanic world. In Old English poetry, æsc was a kenning for "spear" and by extension "warrior." The same root appears in Old Norse askr "ash tree" — the name of the first man in Norse mythology, Askr, was literally "Ash Tree," created by the gods from a piece of driftwood. German Esche and Dutch es are cognates. The separate word ash (combustion residue) has a different origin, from Old English æsce, from PIE *h₂eHs- "to burn, to be dry." The ash tree and fire-ash are thus false friends — identical in modern English but from different PIE roots entirely.

In Norse mythology, the first man was named Askr — literally "Ash Tree." The gods made him from a piece of ash driftwood. The world tree Yggdrasil was also an ash. Meanwhile, in Old English poetry, æsc (ash) was a word for both a spear and a warrior, because spears were made from ash wood.
