A Twitter thread by a user named Lalkaar recently dove into the history of Jugni, and noted that according to Punjabi folk etymology, a woman went out in search of her lost lover, in the guise of a female yogi, or a 'Jogan', which is where the word Jugni comes from.

Sometimes, Jugni is also used to represent spirutial devotion to the Holy Prophet Muhammad (PBUH), and refers to someone who is a 'jugni' of someone who is a devotee of Allah or the Prophet (PBUH).

The historic origin of some of the earliest poems invoking the figure of jugni is also mentioned. "One of the earliest known Jugni poems is set in the 1857 War of Independence against the British, sung by Punjabi rebels crossing the Bastar stream," says the tweet, noting that jugni continued to be associated with rebellion, resistance and war.

In addition to representing love, devotion, spiritual connection and religiosity, and war and resistance, Jugni also represented socio-economic differences & the plight of the poor.
