The term 'THEY'RE TOPS' can be broken down into two crossword solutions: LIDS (4 letters) and ROOFS (5 letters). LIDS are typically found on containers such as jars, bottles, and cans. They are used to seal the container and keep its contents secure. ROOFS are the uppermost part of a building or structure, providing protection from the elements. They are usually made of materials such as wood, metal, or asphalt shingles.
