Usage

When using since as a causal conjunction to mean ‘because’ or ‘given that,’ be aware that in some contexts or constructions the word may be construed as referring to time. For example, in the sentence, Since Mrs. Jefferson moved to Baltimore in the 1990s, she was not aware of the underlying complexities, it is not clear, especially at the beginning, whether since means ‘because’ or ‘from the time when.’ It is often better to simply say ‘because,’ if that is the intended meaning

Origin

Late Middle English contraction of obsolete sithence, or from dialect sin (both from dialect sithen ‘thereupon, afterward, ever since’).
