Word History: The words true and tree are joined at the root, etymologically speaking. In Old English, the words looked and sounded much more alike than they do now: “tree” was trēow and “true” was trēowe. The first of these comes from the Germanic noun *trewam; the second, from the adjective *treuwaz. Both these Germanic words ultimately go back to an Indo-European root *deru- or *dreu-, appearing in derivatives referring to wood and, by extension, firmness. Truth may be thought of as something firm; so too can certain bonds between people, like trust, another derivative of the same root. A slightly different form of the root, *dru-, appears in the word druid, a type of ancient Celtic priest; his name is etymologically *dru-wid-, or “strong seer.”
