In the English translation, it makes sense, but would not tend to be used in normal conversation, in English it's more likely one would say: "The captain and the guard ARE DRINKING tea." Does this make a different sentence in Turkish due to tense or is it the same due to the same gist??
yes it does.
"Kaptan ve bekçi her gün çay içer.": The captain and the guard drink tea every day.
"Kaptan ve bekçi şu anda çay içiyor.": The captain and the guard are drinking tea at the moment.
Ah, fantastic, teşekkürler! You guys (all the moderators) are so eager and quick to help us out, it's amazing! I never knew I liked Turkish before I started this course but now I just love it, more than any other language I've tried studying before, all thanks to you guys ;-)
there is no specific case here like "kaptanı" or "bekcyi" so why its 'the captain and the guard' why not only 'captain and guard drink tea'?
In Turkish, the subject of the sentence can't take the accusative case, so it's assumed. English requires an article in this context, so "captain and guard" would be incorrect by English rules.
both are correct. In general we don't use the -lar suffix if they are doing it together (but we may)
So you meant that whenever we have the "ve" or "and", we refer to them as singular?
