Why not "Let's speak English"?
My thoughts exactly! I checked this in my trusty Collins dictionary, and it's shown as the imperative form of parlare.
So do i with Honor
Exactly! That was an option in a previous lesson. Report it.
My thoughts too. This is the 1st time I've ever got an error using the noi form of a verb with "Let's..."
What's wrong with 'we talk' ?
The problem is in English. When you talk, you 'talk about something' and not 'talk something'.
"We talk English" does not mean anything, you can only say "We talk about English". But then the Italian sentence would be "Parliamo su l'inglese".
Normally we would translate parlare as "to speak" as regards a language, meaning "to speak in (a language)". There is also a colloquial construction in English that allows "Let's talk logistics" or "Let's talk details" and the like.
