The word "punctulation" may seem tricky to spell, but its pronunciation can help shed some light on its spelling. From its IPA (ˌpʌŋktʃuˈleɪʃən), we can see that the "c" is pronounced as a "ch" sound, while the "u" and "e" combination creates a "yoo" sound. The "a" in the second syllable is pronounced as "uh," and the final "tion" ending is commonly used for nouns that denote an action or process. So, overall, "punctulation" refers to the process of punctuating a written text with proper marks.
