The spelling of the word "Ottem" may seem confusing at first glance. However, using IPA phonetic transcription, we can understand why it is spelled this way. The first syllable is pronounced as "ɑt" (like the "a" in "father") and the second syllable is pronounced as "ɛm" (like the "e" in "hem"). The double "t" at the end signifies a glottal stop, which is a brief pause made in the back of the throat. So, "Ottem" is pronounced as "ɑt-ɛmʔ".
