Recognizing the Conditions of “If” or “ei”
There are two parts of a conditional sentences (or, a sentence with an “if” clause/)
The two parts are:
a) The subordinate clause, or “if” clause which states a supposition or condition
b) The principle clause, or “conclusion” clause, which states the result if the “if” clause is fulfilled.
Example: “If you get there early (this is the subordinate or “if” clause)
then you will get a good seat (this is the principle or conclusion clause)
The Greek word ei is translated into English as “if, or whether.” This word will be found in the first part or the subordinate clause of a conditional sentence.
The Greek word an is an untranslated word whose presence in a clause introduces the element of contingency. It will be found in the second part or the principle clause of a conditional sentence.
Here is an example from the Greek interlinear:
ei ek tou kosmou hte
If of the world you were
o kosmos an to idion efelei
the world would its own have loved.
