n. A Hebrew word, meaning ‘ear of corn’ or ‘stream,’ used by Jephthah, one of the judges of Israel, as a test-word by which to distinguish the fleeing Ephraimites (who could not pronounce the sh in shibboleth) from his own men, the Gileadites (Judges xii. 4–6); hence, a test-word, or the watchword or pet phrase of a party, sect, or school.
