If you want to know the reason behind a particular thing (e.g., reason/s behind event, action, scenario), you can use the Filipino question word "bakit." This word translates to "why".
You will sometimes hear Filipinos pronouncing this as "ba-ket" with a letter e on the second syllable (instead of letter i). This is a typical mannerism of some people, pronouncing a syllable consisting of a letter i vowel as letter e (e.g., masakít as ma-sa-két, dikít as di-két, malapit as ma-la-pet).
