It's Divide and Conquer today, with Splitsville being the theme of the day. There are four pairs of Across answers in the grid, with adjacent sections of each pair - separated by a black square highlighted in grey. As indicated by the answer in the middle of the grid - DOESTHESPLITS - these section pairs, read together, reveal something that is commonly associated with the term "split". For example, "Grilled ham-and-cheese sandwich" = CUBAN, and "Amazon swimmers" = ANACONDAS, side by side making BAN/ANA, which indeed often appears in a split. We also have
- SEVEN/TEN - the dreaded impossible split in bowling
- STO/CK - securities are often split to make them more accessible and easier to buy
- LICK/ETY - in the history of the English language, this word has never been written without being immediately followed by the word "split". It's true! Look it up!
