"aveam citit" sună foarte ciudat și nu am întâlnit niciodată. Poate că mai mult ca perfectul din română este similar cu cel din latină ?

My suggestion is to try listening and reading as much Greek as possible, until you get an intuitive feeling about how to order the words. Trying to learn a list of words order rules sounds like nightmare... My teacher has told us in the classes : when we are in doubt about the words order, simply use the romanian words order (this is my native language) and the order will be ok most of the times. I guess that the greek order sounds a bit unnatural for you as english native speaker. In English the grammar is missing certain features such as declination. This means that the words order can influence a lot the meaning: "the dog eats the cat" vs "the cat eats the dog". The order is the only clue for knowing who is eating whom. The Greek allows some flexibility : "ο σκύλος τρώει την γάτα " and "την γάτα τρώει ο σκύλος" mean the same thanks to the nouns declinations (the dog is the one who eats the cat in both sentences because ο σκύλος is nominative case and την γάτα is accusative). But I guess that the first sentence is used usually (while the second would be used only when putting extra emphasis the cat is the one who gets eaten, not someone else).

As far as I know : "σε" means "you" - accusative case. "εσένα" is also "you" accusative , but it's an additional form used for emphasis . "σε βλ'επω" = " (I) see you " "εσένα σε βλέπω" = "(I) see you" . Both sentences mean basically the same, but the second one has some extra emphasis (I see you, not someone else) . But it's incorrect to use "esena" alone ("εσένα βλέπω" would be incomplete).

The two words are usually pronounced with "ye" : (i)eu , (i)este. It's a short "i" , just because it's easier to pronounce. The same happens with "el" (he) and "ea" (she) - pronounced (i)el and (i)a. ( "ea" is pronounced almost like "yeah" ) It is not a mistake to pronounce "e" like in egg , but it is a bit uncomfortable to pronounce and it sounds forced . However, i think that "eu, este, el, ea" are exceptions : most of the words that start with "e-" are pronounced with "e - egg" (element, electric , exemplu , exercițiu ....). So in short: pronounce "ye" for the short words , and "e - egg" for the long words.

It is rare to use the plural surname for referring to an entire family. One example is : family Popescu = familia Popescu = Popeștii . ( Popeștii au o mașină noua = the family Popescu have a new car ) family Damian = familia Damian = Damianii But I'd advise you to avoid using this kind of plurals. I am not sure if it's correct from a grammar point of view and it also sounds too informal. It can even sound a bit ironic , depending on context.

As a simple rule : înainte = before when you are referring to time (ajung inainte de ora 2 - i arrive before 2 o'clock ) . But înainte=ahead/forward when you are referring to a direction, to movement (mergi inainte! walk forwards! ) .

Este o greseala facuta din necunoastere sau din lene. Exista din pacate o tendinta (dar foarte negativa) : parca se scrie din ce in ce mai gresit - mai ales pe Internet (forumuri, facebook, chat ...). (Pentru Ana: mai bine taci decat sa sustii ineptii de genul "cratimele nu sunt necesare". Ba da, sunt foarte necesare. Si nefolosirea lor este analfabetism. Scuze, dar asta e adevarul ).

The main meaning of "marfă" is "merchandise" : Vaporul transportă marfă = the ship transports merchandise/goods . Alternatively, in slang it means "cool" .
