Fanghole is a word used to describe a narrow opening in a rock face where a fang or tooth might be lodged. The spelling of this unique word can be best explained using the International Phonetic Alphabet (IPA) transcription. The first syllable "fang" is pronounced as /fæŋ/ and the second syllable "hole" is pronounced as /hoʊl/. When spoken together, the word sounds like /fæŋhoʊl/. It is important to note the difference in pronunciation between the "a" in fang, which is pronounced as /æ/, and the "o" in hole, which is pronounced as /oʊ/.
