The spelling of the word "extilled" might seem unusual, but it is a valid variant of the word "distill." It is pronounced /ɪksˈtɪld/ (ik-STILD) with the "x" representing "ex-" meaning "out of" and the "t" distinguishing it from "distilled." This spelling is not commonly used but can be found in specialized texts or literary works. It is important to note that the standard spelling of "distilled" is more recognizable and widely accepted in everyday writing and communication.
