Definition of: because

(bi·kôz′) conj.
For the reason that; on account of the fact that; since. [ME bi cause by cause] Synonyms: as, for, since. Because is the most direct and complete word for giving the reason of a thing. Since, originally denoting succession in time, signifies a succession in a chain of reasoning, a natural inference or result. As indicates something like, coordinate, parallel. Since is weaker than because; as is weaker than since: either may introduce the reason before the main statement; thus, since or as you are going, I will accompany you. Often the weaker word is the more courteous, implying less constraint. Antonyms: although, however, nevertheless, notwithstanding, yet.
