“For” is a coordinating conjunction. Coordinating conjunctions are words placed between other words, sentences, phrases and clauses of equal importance. They are also known as coordinators and are used to give equal emphasis to a pair of main clauses. A clause is a statement that is either true or false. This is also known as a proposition. There are just seven coordinating conjunctions in English. They are “for, and, nor, but, or, yet, so”. “For” as a coordinating conjunction is considered archaic or non-standard English of today! “For” in this case is used more for literary usage. The word “Because” is a subordinating conjunction. It is often used to replace the word “For” as a coordinating conjunction. Although not grammatically correct, “Because” is often used in spoken English. There is one main difference when “For” is replaced with “Because”. You “CAN” begin a sentence with “Because” while you “CANNOT” begin a sentence with “FOR”. Just remember, most grammar rules in English have exceptions. This is just one!
