Common mistake

A very common wedding writing error: "She walked down the isle" (correct: aisle — the church walkway). Or writing 'aisle' when describing a Caribbean island.

Trick to remember it

'Aisle' has a silent S like 'island' — both words hide a letter in plain sight. 'Isle' is short and simple, like a small island easy to overlook.

Quick rule

Is it the walkway between seats or shelves? 'Aisle'. Is it a small or literary island? 'Isle'.

Did you know?

'Aisle' gained its silent S through contamination from the French 'isle' (island). In Old French, 'aisle' meant a wing of a building (church nave), and scribes added an S by analogy with 'isle'. The S was never pronounced but stuck in the spelling — one of many silent letters English inherited from French influence after the Norman Conquest.
