The word "because" is commonly used in English language to indicate a reason or cause. However, there are many other synonyms that can be used in its place. For instance, "since" is often used to denote a reason or explanation, while "as a result of" highlights a specific consequence or outcome. Examples include "due to," "owing to," and "on account of." These words work as a better fit in academic or formal writing where variation is desired. Also, "on the grounds that" might be employed to express the underlying logic. By applying different expression to communicate causality, a writer or speaker can imprint greater clarity to their audience.
