Everyone knows the problem with spell-check: your word might be spelt right, but it may be the wrong word. It happens all the time. You’re writing a paper or texting a friend and have to ask yourself, “Is it affect or effect? A while or awhile?” Sometimes, even the most seasoned writers have to stop and do a quick search (Google) to double-check themselves. English is full of confusing words that sound alike but are spelt differently. It’s also full of words that share similar (but not identical) meanings of which chances are high of being misused. They either look alike, sound alike or, worst of all, look and sound alike but have completely different meanings.


With these two words, the main difference is grammatical, although they’re pronounced slightly differently. Usually, affect is a verb and effect is a noun, and they’re used when talking about the results or consequences of particular actions.

    • I’m worried that your lazy habits will affect your studies (your lazy habits will have a bad effect on your studies).
    • Before you start an argument with your boss, consider the effects of your actions (before you start an argument, consider how your actions will affect the situation).
