Etymology[edit]

From the Latin quaternārius (containing or consisting of four), from quaternī (four each”, “four at a time) + -ārius (whence the English suffix -ary); compare the French quaternaire.

Pronunciation[edit]

  • (file)

Adjective[edit]

  1. (proscribed) Of fourth rank or order.
  2. Of a mathematical expression containing e.g. x4.

Usage notes[edit]

The etymologically correct fourth ordinal from Latin (following tertiary) is quartary, but quaternary (from the distributive number instead) is common, particularly in biology.
