"Tenete gli occhi aperti."

Translation: Keep your eyes open.

[Viaggiatore]

"Keep" is the usual meaning: http://www.wordreference.com/iten/tenere

Doesn't Tenere mean to have? not to keep?

[DrFoard]

Can someone explain please when vostro (vostri) can be implied (as in this case) and when it must be explicit? I don't quite see the pattern.

By my understanding, the Italian translation of "Keep your(pl) eyes open." would more properly be "Tenete i vostri occhi aperti." or "Tenete aperti i vostri occhi." if "open" is emphasized, but I recognize that people don't seem to speak like this.

Maybe this given translation is idiomatic rather than literal? Much like "Eyes open!" would be a common idiomatic way of saying the same thing in English, where "keep" and "your" are both implied.

With body parts, you generally use the definite article instead of a personal pronoun

I was suprised that Leave your eyes open, gave me mistake

[Viaggiatore]

That's not the way people would ordinarily say it. You control your eyes, you don't leave them.

[myselfandi]

Imparative? Do we know that already?
