Your examples are right. Just remember that “effect” is usually a noun and “affect” is usually a verb.
From here:
" 1. Determine if the usage calls for a verb or a noun.
If a verb is needed, 95 percent of the time or more the word you want is “affect.” It means to change or to alter. “The weather affects our moods.” “Nutrition affects health.” “The seasons affect trees and flowers.” “The quality of your work affects your grade”
3.The occasional need for “effect” as a verb arises when the narrow meaning “to cause or to bring about” is appropriate. These rare occasions often occur in some form of the expression “to effect a change” or, in police jargon, “to effect an arrest” (to cause or make an arrest happen). Nevertheless, it’s still best to avoid, particularly in the last example because it’s simply police jargon, and it’s good to avoid jargon.
When a noun is required, the word is almost always “effect.” This means “a result.”“The effect of diligent study habits is better learning.” “The effect of making the correct choice is a better grade.” (Do you sense a theme here?)
“Affect” can be a noun, but its use is almost entirely reserved for psychological jargon. You could have a long career as a writer and editor and never encounter the need for the noun “affect.”
So be ready to make almost all verbs “affect.”
And be ready to make virtually all nouns “effect.”
And of course the unwritten mnemonic is RAVEN: Rememeber, Affect is a verb and effect is a noun
The other one is Affect = Alter and Effect = End. Basically if you can substitue end the word should be effect and if you can substitute alter then the word should be affect. That’s less obvious but to use the exmaples given above:
“The end of diligent study habits is better learning.” That makes sense, whereas “The alter of diligent study habits is better learning” is meaningless. So the desired word must be effect.
“Nutrition alters health.” That makes sense. "Nutrition ends health.” That might make sense, but it’s not what we mean, so the desired word is affect.
For the sake of completeness, I’ll just throw out that “affect” also has another use as a verb, meaning “to put on a pretense of”. Both of these come from the OED Second Edition:
cosmodanm you have it right. And people have given good, sound advice.
But don’t worry about this. Really. Just write what you want, and then hand it over to a professional editor, who will fix everything. I don’t know that you ought to even try this at home. There ought to be warnings on the dictionary.
(Wouldn’t English be a fun language to learn as a second language?
What about the following: “Nutrition has an affect/effect on health.” It’s a noun here, but does not mean result. It means alteration which more closely links it with the verb affect. It’s also not a rare usage by any means.
In my never-ending quest to out-geek NoClueBoy, I’ll just cite a Star Trek related example of the “Dickensian” use of “affect”. In one ep, Data the droid experiments with the mysterious ways of love, getting entangled with some blonde chick who had never been seen before and was never seen again (c’est la vie). In one scene, he tries to act more appealingly and ends up giving this creepy, over-accented, rather smarmy perrformance, causing her to accuse him of being affected.
Of course, she’s just a stereotypical indecisive clingy high-maintenance bitch, but what you gonna do?
It’s true that “affect” is used as a noun mainly by psychology types, and so it’s probably not the word you’ll be looking for in common speech or writing, but let’s end the suspense here: all it means is a feeling or emotion, as opposed to a thought.
This is good to know when you’re looking for a noun and are not sure whether you want “effect” or “affect”…
The hurricane had a terrible affect/effect on the banana crop.
“Affect,” meaning feeling or emotion, makes no sense here. We want “effect” (result, consequence, as in “cause and effect”).
Well, I don’t remember the exact quote (shame on me), but she definitely accused him of being affected. And then he yelled (!) back “You don’t tell me what to do, you’re not my mother!” thus breaking the “no-contraction rule” for the 75th and 76th time.
