dahil

Dahil is a conjunction in Filipino/Tagalog that means "because" or "for the reason that." It introduces a clause that explains the cause or justification for what is stated in the main clause. When the reason comes before the main clause, the structure is typically [Dahil + clause], [main clause], for example: "Dahil masama ang panahon, hindi kami natuloy."

The phrase dahil sa is also common and attaches to a noun or noun phrase to express cause or attribution: "Dahil sa ulan, natigil ang klase." This usage functions like the English "due to" or "because of." In both cases, dahil is a coordinating tool that links reason to result.

Usage notes and variation: dahil is widely used in both spoken and written Filipino. It can carry a neutral or formal tone, but it is generally more formal than the colloquial synonym kasi. In more formal writing, sapagkat or dahil sa sometimes appears, with sapagkat being particularly common in literary or expository contexts. The choice among these options can influence tone and register.
