n. (plural of practicum English)
Wikipedia
Práctica is a term for an informal event where Argentine tango or Salsa is danced. It is similar to a Milonga. However while a Milonga is rather a formal event where dancers socialise, on a Práctica dancers focus on practicing the dance.
The music played is similar to the music played on milongas, though the flow of songs is not necessarily broken up by cortinas. Prácticas are often held on a regular basis (usually weekly).
A practica was an annually printed booklet containing astrological predictions for that year. They were a popular genre of printed work in German-speaking territories from the 15th to the 17th century. Wenzel Faber von Budweis and Johannes Virdung were two leading authors in the genre.
