Quick answer
Sail is for boats; sale is for selling. Memory hook: sail has an i, like the mast of a boat, and sale is the noun that goes with sell.
The core difference
Sail is about travelling by boat or the fabric that catches the wind, while sale is about selling things or reduced prices.
- sail — the fabric on a boat, or to travel by boat: We sailed past the lighthouse just before sunset.
- sale — the act of selling, or a period of reduced prices: She bought the coat in the sale.
- sail can also mean to move through something easily: She sailed through the exam.
How to tell them apart
Ask whether the sentence is about water or wind, or about money and shopping. Boats and easy progress use sail; shops, prices and selling use sale.
The i in sail can stand for the tall mast of a boat. Sale ends in -le, and it is the noun that pairs with the verb sell.
Where the mix-up shows up
The most common slip is on shop signs and adverts, such as sail now on instead of sale now on. The opposite error appears in writing about sailing, such as set sale instead of set sail.
