The term 'SOME SHELLS' can be broken down into three separate words: PASTA (5 letters), AMMO (4 letters), and SWEATERS (8 letters). PASTA is a type of food made from unleavened dough of wheat flour or semolina, usually cooked in boiling water. AMMO is short for ammunition, which is the material fired, scattered, dropped, or detonated from any weapon. Lastly, SWEATERS are garments worn to keep the body warm, typically made from wool or cotton.
