Notation for propositions with small letters p, q, r,.....in contrast with predicate letters denoted with big letters P, Q, R,... edit

There is some problem with the notation used for propositions or propositional variables in this article using big letters P, Q, R, S,.. usually asigned to predicate symbols P, Q, R,..while propositions are denoted with small symbols p, q, r, s. The edit specifying this notation I see it has been reverted.--185.53.196.112 (talk) 21:20, 5 October 2019 (UTC)Reply
