The spelling of the phrase "dost battle with" follows typical English orthography rules. "Dost" is an archaic form of the verb "do" used only in modern English to express emphasis or form questions. The pronunciation of "dost" is /dʌst/. "Battle" has a double "t" because of the ending "-le" which creates a stress on the last syllable. The pronunciation of "battle" is /ˈbæt.l/. Finally, "with" follows the standard way of spelling the phoneme /w/ and the vowel sound /ɪ/ represented as "i". The pronunciation of "with" is /wɪð/.
