If you are translating into English from Latin, conditional sentences are identified by either si or nisi of it is a negative statement, translated as if or unless respectively. Once that has been spotted, you have identidfied the conditional part of the clause, which is either followed or preceded by the main clause. The way in which the type of conditional clause governs the verb forms that follow can be complicated; however, here is a table to simplify it. The difference between open and remote clauses is that remote clauses contain a 'would' or 'were to' in the each clause (e.g. if I were to eat this food, I would no longer be hungry).
