This is a transliteration into Tagalog of the English word.
tsásis
chassis
Because this word came from the French, the final “s” is often omitted by English speakers; they may also substitute an “sh” sound for consonant digraph “ch.”
Chassis is the supporting frame of a structure, such as of an automobile.
