re
/ˈre/ · B1 · adv
very, so, super
The intensifying prefix re- (rebueno = really good) broken off into its own word
Spanish puts re- in front of words to boost them: relindo means very pretty. In Argentina and Uruguay, speakers turned the prefix into a word of its own: es re fácil = it's super easy; me gusta re mucho = I really like it.
