"Father is not strict, but kind."
Translation:Pater non est severus, sed benignus.
Just want to say, to the creators (of this course) out there, great job. These sentences, challenging as they are, make sense, unlike some of the other language courses. Thank you !!! I really loved the one about, Livia, where are the men? Always the question !!! LOL. XOXO
It is not the copula which needs negating (i.e., non est), but severus. Thus “pater non severus sed benignus est” (as several have already suggested).
