How to build BACKFLOW from the tiles

In 7 Little Words you don't type the answer — you assemble it from the puzzle's shared tile bank, and every tile is used exactly once across all seven answers. Puzzle 4's tiles for October 17, 2026 are:

BAC · KFL · OW · AN · GL · IA · BO · UND · CLO · MP · CL · OT · HES · LI · NE · LAG · NIA · PPE · TOO · LS

BACKFLOW is built by combining the tiles BAC · KFL · OW in order. Because those tiles come out of the shared bank, locking in BACKFLOW early also narrows what's left for the other six clues.
