In some languages, such as Finnish, Estonian and Breton, the ordinal directions have names that are not compounds of the names of the cardinal directions (as, for instance, northeast is compounded from north and east). In Finnish those are koillinen (northeast), kaakko (southeast), lounas (southwest), and luode (northwest).
