Blood fluids crossword clue
17 Down · WSJ Crossword, October 16, 2026 · 4 letters
Explanation
The answer to “Blood fluids” is SERA. It appears as 17 Down in the Wall Street Journal crossword of October 16, 2026, a Friday puzzle titled “On the Wrong Track” by Brad Wiegmann, and it fills 4 squares running top to bottom from row 1, column 21 of the 21×21 grid.
The clue is a straightforward definition, so the answer is a direct synonym or a factual match for the words as written. The entry begins with S and ends with A, and contains 2 vowels and 2 consonants. If you are working from the crossings, two or three confirmed letters from the Across entries should be enough to lock it in. Friday puzzles are the Journal’s contest crosswords with a hidden meta answer, so expect the rest of this grid to be pitched at the same level.
