Why this word is great
INDOLES — [Noun] The unalterable core of a being; the inborn essence that persists beneath all acquired layers. From Latin indolēs ("inborn quality, nature"), from indu- ("within, in") + -olēs ("growing")—a word that blooms from the root, like a sapling from a seed. Unlike "temperament" (which bends to circumstance) or "habit" (which is woven by repetition), indoles is the bedrock, the immutable grain in the wood. It is the wolf cub that snarls before it learns to hunt, the vine that twists sunward without being taught, the child who hums in perfect pitch before ever hearing music—proof that some things are written in the bones long before life begins to erase them.
