Shone versus Shined
No one would fault you if right about now you were wondering: if “shone” is the past tense of “shined,” then why doesn’t anyone say “I had my shoes shone yesterday”?
The answer is that in modern writing, it’s considered archaic (and therefore, wrong) to use the word “shone” to refer to having shined anything so mundane as shoes, silverware or windows. That said, it’s perfectly acceptable in modern writing to say that after you shined your shoes, your silverware, or your windows, they shone brightly.
Shone is a past and past participle form of the verb shine, when shine is used as an intransitive verb meaning to emit light. Shone comes from the Old English word scinan, meaning shed light, be radiant, illuminate.
Discreet versus Discrete
Discrete means individual, separate or distinct.
Discreet means careful, cautious or evidencing good judgement.
To remember the difference, think about one “e” versus two. Use one “e” to refer to something singular. Use an extra “e” to show extra care.
That said, “discretion” requires only one “e,” but when you exercise discretion, you’re adding two more.
Emigrate versus Immigrate
When you leave your country to permanently live in another, you emigrate.
When you arrive in another country to live permanently, you immigrate.
To keep these two words straight, think about them in alphabetical order: you emigrate before you immigrate. You’re an emigrant before you become an immigrant. Or simply think about the fact that when you immigrate to a new country, you must pass through that new country’s “Immigration Department.”
