"Tomax" is a made-up word, and therefore has no definitive spelling or meaning. Using the International Phonetic Alphabet (IPA), we can transcribe the sounds in "tomax" as /təʊ.mæks/. The first syllable is pronounced with an open-mid back rounded vowel (/əʊ/), followed by a voiceless alveolar plosive (/t/). The second syllable starts with a voiced bilabial nasal (/m/), followed by the vowel /æ/ and the voiceless velar fricative (/ks/). However, without context or origin, there is no "correct" way to spell "tomax."
