*can*- (2) vb. "command, order" (give an order) or (with things as object) "demand" _(PM:361-362; where various derivatives of the stem KAN- are listed; the verb _can_- is not directly cited, but seems implied by the statement "in Quenya the sense command had become the usual one". The undefined verb _canya**- listed elsewhere [PE17:113] may also be taken as the actual verbal derivative that Tolkien here refers to.)
