The spelling of the word "Bohler" can be explained using the International Phonetic Alphabet (IPA). The initial sound is a voiced bilabial stop or /b/ followed by an open-mid back rounded vowel or /o/. The next sound is a voiceless alveolar fricative or /s/ and the final sound is a voiced alveolar approximant or /l/. Therefore, the correct spelling is "Bohler" with a "b" sound followed by an "oh" sound, an "s" sound and an "l" sound.
The word Bohler originates from a German surname. It is derived from the Middle High German word buhelære, where buhel means hill and ære refers to someone who cultivates, owns or inhabits that hill. Over time, the spelling and pronunciation of the name evolved to Bohler.
