"The wife is also strict."
Translation:Uxor quoque est severa.
Latin syntax is relatively flexible, so be careful with your "shoulds". Also, there is an important distinction between a direct object of a transitive verb, which is the O in SOV (subject object verb), and a subject complement that comes with a stative verb. This is why it is common to see SVC (subject verb complement) in Latin.
(Ego) sum = I am, (Tu) es = Thou art, (Is/ea/id) est = He/she/it is, (Nos) sumus = We are, (Vos) estis = Ye/You are, (Ei/eae/ea) sunt = They are.
However, as you're learning Spanish, which is descended from Latin; est = es, sunt = son.
(Ego) sum = Yo soy, (Tu) es = Tu eres, (Is/ea/id) est = él/ella/ello es, (Nos) sumus = Nosotros somos (Vos) estis = Vosotros sois (Ei/eae/ea) sunt = Ellos/ellas son.
