"Marbl" is not a correctly spelled word in English. The correct spelling is "marble", which is pronounced as /ˈmɑːrbl/ in IPA phonetic transcription. The phoneme /b/ at the end of the word is voiced, which means the vocal cords vibrate while making the sound. It is important to use correct spelling in written communication to avoid confusion and misunderstandings, as well as to display proper language skills.
The word "marble" comes from the Middle English word "marbel" or "marvel", which was derived from the Old French word "marbre". This Old French term originally came from the Latin word "marmor", which in turn was derived from the Greek word "mármaros". The Greek term was used to refer to shining or gleaming stone, particularly marble.
