You’re and Yore are easily confused words.
The spell-check application of most word processing software programs would not catch a slip-up of these two words. Spell-check is looking for words that aren’t in its dictionary, and words that resemble words in its dictionary but are possibly spelled wrong. Spell-check isn’t perfect. It doesn’t know and can’t guess what word you wanted or what word you meant, it can only judge the words on the page. If you used words that are all spelled correctly, it gives you a pass anyway.
Autocorrect suggests words that start with the same letters. It’s suggesting what word you may want to save time, but quite often, its suggestions are pretty off base. They don’t help you out, but they do make you laugh.
You’re (pronounced “yoo-uhr”) is a contraction of the phrase “You are.” “You” is a pronoun used when talking directly to someone else, and “are” is the corresponding verb tense of “to be.”
Yore (pronounced “yuh-awr”) is a noun. It is usually used in the phrase “of yore,” meaning, in the days of the distant past.
The following story uses both words correctly:
Yuri was often told, “You know, you’re not a typical teenager.” He loved to read and write stories. He found it easier to relate to historical figures of yore than his classmates.
After hearing this one too many times, he responded, “You say that like it’s a bad thing.”
