Resumen:
In this paper we introduced and studied term quasivarieties, also called term varieties when the quasivariety considered is a variety. Roughly speaking, they are quasivarieties in which there are some terms characterizing relative principal congruences in any member of that quasivariety (if the quasivariety considered is a variety, the relative principal congruences are exactly the principal congruences in any algebra of that variety). The definition of term quasivariety is motivated by thefact that there are many quasivarieties of interest for algebraic logic for which the procedure to obtain a description of the relative principal congruences is exactly the same. We also studied relative compatible functions in term quasivarieties.
