Everyone knows the problem with spell-check: your word might be spelt right, but it may be wrong. It happens all the time. You’re writing a paper or texting a friend and must ask yourself, “Is it affect or effect? A while or awhile?” Sometimes, even the most seasoned writers have to stop and quickly 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, which are likely to be misused. They either look and sound alike or, worst of all, look and sound alike but have entirely different meanings.


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

    • I’m worried that your lazy habits will affect your studies (your lazy habits will hurt 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).

Hung is the past of the verb to hang, most of the time.

    • I hung the painting on the wall, and I hung my clothes on the clothesline.

Hanged is the deadly exception, as it’s the past tense of hang in a particular situation. Hang can also mean executing a criminal by hanging them with a rope. In that case, the past tense of hang is hanged.

Amount refers to a quantity of something.

Many native speakers use these two words with the same meaning – bored or not interested. That’s undoubtedly the meaning of uninterested, but it’s not the meaning of disinterested.
