How to build MCKNIGHT 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 9's tiles for September 19, 2026 are:

SAG · UA · RO · LOP · PER · EXM · OOR · MCK · NI · GHT

MCKNIGHT is built by combining the tiles MCK · NI · GHT in order — 3 of the ten.

What this unlocks

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.
