The correct spelling of the word "pensiv" might be a source of confusion for some. The correct spelling is actually "pensive" /ˈpɛnsɪv/. The symbol /ˈpɛns/ represents the stressed syllable, while /ɪv/ represents the unstressed ending. Phonetically, the word starts with a voiceless bilabial stop /p/, followed by a lax vowel /ɛ/, a voiced alveolar nasal /n/, a voiceless alveolar fricative /s/, and ends with an unstressed vowel /ɪ/ and voiced labiodental fricative /v/. Now that we know the correct spelling, we can confidently use this adjective to describe someone who appears deep in thought.
