"I build cities."

Translation: Urbes condo.

[Mark644879]

I build cities unlike that lazy a.. Marcus.

[DaVdro]

Says you, Mark.

[SeanMeaneyPL]

I think "construo" should work. I have suggested it.

[JohnSmith2142]

Did Duolingo rightly complain that I used construo instead of condo?

[Pauline703576]

Condere means build a totally new city

[PERCE_NEIGE]

Rather "founding" it I think.

[EllieSwell]

It says 'urbis' is a typo, but wiktionary says it can be '-es' or '-is'. Is that right?

[wyrmwood]

Why is 'ego' not used for 'i'?

[JohnSmith2142]

As long as the verb is conjugated, you can but don't need to tell the pronoun. In modern Spanish, it's the same, and I think in any language that has a sufficiently detailed and unambiguous system of verb-conjugation.
