"Mi hijo es inteligente."
Translation:My son is intelligent.
As of September 25th, 2018, it hasn't been fixed. I don't see an option to report it.
I'm assuming so. Word for word translations don't always work, and not all words in one language have a word in another language. In English intelligent is synonymous with smart although it is a stronger word, so inteligente is probobly the closest translation. I don't know for sure so don't take my word as scripture, but that's how I understand it.
I agree with T.J. Also to add that listo means smart when used with ser.
Mi hijo es listo. My son is smart.
Mi hijo está listo. My son is ready.
Repeated the phrase completely and correctly and was given an incorrect!!!
