Macrofamily
A macrofamily (also called a superfamily or superphylum) is a term often used in historical linguistics to refer to a hypothetical higher-order grouping of languages, composed of multiple language families and/or isolates. Some scholars, such as Campbell, view this designation as superfluous or redundant, preferring "language family" for those classifications for which there is consensus and "distant genetic relationship" for those which lack consensus, whether due to lack of documentation, lack of scholarship, or time depth thought by linguists too great for accurate reconstruction, but which have not been outright rejected or definitely discredited.
