Inits. for this puzzle's shaded squares

USS

["Here’s a helpful hint for the clue:\n\n**\"Think of the letters that start the words for the white parts of the grid.\"**\n\nThis nudges the solver toward considering \"unshaded squares\" (the white squares) and their initials, without directly giving away \"USS.\" It’s easier than the original clue but still requires a small leap of logic."]

The clue **"Inits. for this puzzle's shaded squares"** leads to the answer **"USS"** through the following reasoning: 1. **"Inits."** is a common crossword abbreviation for "initials," indicating that the answer consists of the first letters of a phrase. 2. **"This puzzle's shaded squares"** refers to the black squares in a crossword grid, which are typically shaded to separate words. 3. The initials of **"shaded squares"** are **"S" (shaded) + "S" (squares)**, but this would give "SS," which doesn't match the answer. 4. Instead, the phrase likely refers to **"Unshaded Squares"** (the white squares where answers are written), whose initials are **"U" (Unshaded) + "S" (Squares) = "US."** 5. However, the answer is **"USS,"** suggesting an extra **"S"**—possibly implying **"Unshaded Squares in the puzzle"** (with "in the puzzle" adding another "S" for "Squares"). 6. Alternatively, it may be a playful reference to **"Unshaded Squares"** being the focus of the puzzle, with the extra "S" standing for "shaded" as a misdirection. The most straightforward interpretation is that **"USS"** stands for **"Unshaded Squares"** (with an extra "S" for stylistic or thematic reasons in the puzzle). This is a clever bit of crossword wordplay where the solver must think beyond the obvious.
