Translation:Yesterday we went out for a walk on a cold day.
Can "'caminar" be translated as "walking" here? As in "we went out walking". "we went out to walk" seems at best awkward to me because "to walk" implies present tense, but it was yesterday. Also in this case "out" seems redundant to me, although I get that salir means to leave or go away from. Just not clear to me how you walk without going out...unless you're just pacing.
My understanding is that Spanish doesn't use the gerund nearly as often as in English...and usually uses the infinitive instead. I don't think you can use caminando in this context...but obviously if I was sure, I wouldn't have posted the question. Note also that even in the present tense, the "ing" form in English can apply: "aprendo" can be "I learn" or "I am learning". I've noticed that Duo has added many more preferred translations using the later.
Hi Julio, this is the Spanish course. These exercises are geared toward learning Spanish and many people have become quite proficient from Duolingo.
I'm not sure where you got the idea that this wouldn't improve your Spanish. In this sentence alone you practice eight vocabulary words, adverb placement, using an infinitive with a conjugated verb, prepositional phrases, article and adjective agreement.
