Why the answer is EFFLUENT

EFFLUENT fits the clue “liquid industrial waste” on Puzzle 10 for Friday, September 18, 2026. At 8 letters, it's one of the words you assemble from that puzzle's bank of ten tiles — and locking it in early clears tiles for the other three clues.

How to build EFFLUENT from the tiles

In 4 Little Words you don't type the answer — you assemble it from the puzzle's bank of ten tiles, each two to four letters long, and every tile is used exactly once across the four answers. Puzzle 10's tiles for September 18, 2026 are:

RIC · KEY · BI · RYA · NI · EF · FLU · ENT · BRA · MLEY

EFFLUENT is built by combining the tiles EF · FLU · ENT in order — 3 of the ten.

What this unlocks

Because the ten tiles cover the four answers exactly, with none left over, placing EFFLUENT removes 3 tiles from play and makes the rest of Puzzle 10 measurably easier. If this was your third answer, the tiles still sitting on the board are the fourth word — you can often assemble it without working out the clue at all.
