The spelling of the word "prager" can seem confusing, but it can be explained using the International Phonetic Alphabet (IPA). The IPA transcription for "prager" is /ˈpreɪɡər/. This tells us that the word begins with the sound of "pr" followed by a long "a" vowel sound represented by the letter "a". The following "g" is pronounced with a soft "g" sound, and the word ends with the sound of "er", represented by the letters "er". Therefore, the correct spelling of the word is "prager".
