Why those letters? (public/private)

[LatinaAlumna]

There are several NALFO organizations that have "public" phrases that correspond with their letters:

Lambda Upsilon Lambda = La Unidad Latina
Chi Upsilon Sigma = Corazones Unidos Siempre
Lambda Upsilon Alpha = Latino America Unida
Lambda Sigma Upsilon = Latinos Siempre Unidos
Lambda Pi Upsilon = Latinas Poderosas Unidas
Lambda Pi Chi = Latinas Promoviendo Comunidad
Sigma Lambda Upsilon = Senoritas Latinas Unidas
Alpha Pi Sigma = Amigas Para Siempre

Now, whether the letters have meaning beyond the public phrase would only be known to members...
