The word "punctulated" is spelled with the letter combination "ctu" which can be tricky to pronounce correctly. Using IPA phonetic transcription, the word would be: /ˈpʌŋktʃuˌleɪtɪd/. The "ctu" can be pronounced as "k-t-yu" with a brief pause between the "k" and "t" sounds. The word means "marked with dots or points" and may be used in scientific or technical writing, but it is not commonly used in everyday conversation.
