KK: /ˈʃɪbəlɛθ/
A word, phrase, or custom that is used to identify members of a particular group, often revealing outsiders or distinguishing between different groups.
The term 'y'all' is a shibboleth that indicates someone is from the southern United States.
Shibboleth originates from Hebrew 'שִׁבֹּלֶת' (shibboleth), meaning an ear of grain or stream. In the biblical context, it was used as a test word to distinguish between different groups of people based on their pronunciation.
Think of the Hebrew word for an ear of grain, which was used as a way to identify people by how they pronounced it. This helps you remember that a shibboleth is a way to distinguish one group from another.
