Thiago introduces the present tense, focusing on spelling rules for third-person verbs. He explains the basic rule of adding 's' and special cases for verbs ending in CH, SH, X, Z, S, and O, which require 'es'. For verbs ending in Y, if preceded by a vowel, 's' is added; if by a consonant, 'y' is replaced with 'ies'.
