“sale” vs. “sail”
Use "sale" for buying and selling (a noun only); use "sail" for the canvas on a boat or the act of traveling by water (noun or verb).
sale
"Sale" is a noun referring to the act of selling something, an exchange of goods or property for money, or a period when merchandise is offered at reduced prices ("everything is on sale this weekend"). It comes from Old Norse "sala," related to Old English "sellan" (to give, to sell), and it functions almost exclusively as a noun in modern English — you have a sale, you make a sale, you go to a sale, but you don't "sale" something as a verb.
sail
"Sail" can be either a noun naming the piece of fabric that catches wind to propel a boat, or a verb meaning to travel on water using such fabric (or, more loosely, to travel by any watercraft, or even to glide smoothly through the air, as in "the frisbee sailed across the yard"). It comes from Old English "segl," part of a long Germanic seafaring vocabulary. Unlike "sale," "sail" does double duty as both noun and verb, and its meaning almost always involves movement, wind, or water in some form.
The real distinction
The clearest dividing line is commerce versus movement: "sale" belongs to the world of buying and selling, while "sail" belongs to the world of boats, wind, and travel. A useful memory check is that "sale" rhymes conceptually with "deal," since both concern transactions, while "sail" conceptually pairs with "gale," since both concern wind and open water. Confusion tends to arise in phrases where both could theoretically apply to a boat, such as when a yacht itself is being sold — in that case, the boat is "for sale" (the transaction) even though it "has sails" (the equipment), and writers sometimes let the nautical topic bleed into the wrong spelling. Grammatically, "sale" is a pure noun that never conjugates, whereas "sail" flexes as a verb across tenses — "sailed," "sailing," "will sail" — which gives you another quick test: if the word needs to change form to fit past or future tense, you're dealing with "sail," not "sale." Another small but useful clue lies in compound words: "sale" appears in commercial compounds like "wholesale," "resale," and "garage sale," all firmly rooted in buying and selling, while "sail" appears in nautical compounds like "mainsail," "topsail," and "sailboat," all firmly rooted in wind-powered travel. Neither word ever crosses into the other's compound family, so if you're unsure which spelling a longer word needs, checking whether the compound concerns money or wind usually settles it immediately.

Memory trick
Think of the "i" in "sail" as standing straight up like a ship's mast — a tall, narrow sail catching wind. "Sale," with its "a," pairs naturally with other transaction words like "trade" and "bargain," none of which involve wind or water. If the sentence is about money changing hands, there's no mast in sight, so skip the "i" and write "sale."
