The word "Appensio" is spelled with two p's because it is derived from the Latin word "apprehensio," meaning "to seize or grasp." The first syllable, "ap," is pronounced with a short "a" sound as in "cat," and the second syllable, "pen," is pronounced with a short "e" sound as in "pen." The last syllable, "sio," is pronounced with a "sh" sound as in "mission." So the IPA transcription for "Appensio" would be /æpˈɛnʃioʊ/.
