The term 'PART OF THE MOUTH' can be broken down into two crossword solutions: the UVULA (5 letters) and the ROOF (4 letters). The UVULA is a small, fleshy projection that hangs from the back of the soft palate at the top of the throat. It is responsible for producing certain sounds in speech. The ROOF of the mouth is the upper surface of the oral cavity, which is made up of two parts: the hard palate and the soft palate. The hard palate is the bony front portion of the ROOF of the mouth, while the soft palate is the fleshy back portion. Both the UVULA and the ROOF of the mouth are important parts of the mouth that help us to speak and swallow.
