How the test tells a pair apart
The sentence decides. For sole the test reads A pebble stuck in the sole of my boot, so soul is wrong: the results say That word sounds the same, then show the sentence. Its and it's get a line about the apostrophe instead. I'll in List 2 needs its capital I while Capitals count is checked, and each contraction needs its apostrophe.
What the twelve lists hold
Lists 1 and 2 have the famous sets and the contractions (its, it's; whose, who's). Lists 3 to 5 have short pairs and sets of three (cent, scent, sent). Lists 6 and 7 pair a word with an ed or s ending (fined, find; claws, clause). Lists 8 to 12 have harder pairs (haul, hall; wring, ring).
- Stationery with an e is paper, like envelope; stationary with an a stays in place.
- Principle and rule both end in le; the principal is a person.
Questions and answers
What is the difference between a homophone and a homonym?
Homophones sound alike and are spelled differently, such as meet and meat. Homonyms, strictly, share both sound and spelling, such as bat the animal and bat the club; many people use the word for any sound-alikes. Every set here is homophones.
Which homophones come in threes?
Six sets: their, there and they're; to, too and two; aisle, isle and I'll; heal, heel and he'll; cent, scent and sent; vain, vane and vein.
Do these pairs sound the same in every accent?
In most American speech, yes. Wiktionary lists each set as sounding alike and notes that a few, such as horse and hoarse or for and four, are still said differently in some accents.
