Accept vs. Except

Accept (verb) - to receive

  • I accepted all my birthday gifts with gratitude.

Except (conjunction) - apart from; otherwise than; were it not true

  • When Susan travels, she packs everything except the kitchen sink.

Affect vs. Effect

These two are tricky because each word can act as both a noun and a verb. While it's common to see "affect" working as a verb and "effect" working as a noun, both can operate as different parts of speech. Let's take a look:

Affect (verb) - to have an effect on; influence; produce a change in; to stir the emotions

  • The dog's death affected his owners.

Affect (noun) - feeling or emotion, as it relates to psychology

  • One of the telltale signs of love is persistent positive affect.

Effect (verb) - to create or to cause

  • The new principal is trying to effect positive change in her students.

Effect (noun) - anything brought about by a cause or agent; result

  • The new speed limit law had little effect on the speed of the motorists.

Here's a concise summary of it all:

  • The manager's attempt to effect (v.) positive change on employee affect (n.) had the unintentional effect (n.) of affecting (v.) punctuality.

A Lot vs. Allot

A lot (noun phrase) - many

  • A lot of people came to the party.

Note - "A lot" is always two separate words. "Alot" is not a real word.

Allot (verb) - to distribute, give or assign

  • Fifteen minutes were allotted to each of the speakers at the conference.

Allusion vs. Illusion

Allusion (noun) - an indirect reference

  • The Austin Powers movies often make allusions to the James Bond films.

Illusion (noun) - a false idea or conception; belief or opinion not in accord with the facts; an unreal, deceptive, or misleading appearance or image

  • The magician created the illusion that he was levitating.

Awhile vs. A While

Awhile (adverb) - for a while; for a short time

  • The guests planned to stay awhile.

A while (noun) - for a short time; when "while" is used as the object of the preposition (i.e., for a while), then the "a" is separated from the "while"

  • The guests planned to stay for a while.

Bad vs. Badly

Bad (adjective) - not good

  • Your feet smell bad.

Badly (adverb) - not well; in a bad manner; harmfully; incorrectly; wickedly; unpleasantly

  • Charlotte plays tennis very badly.
  • The people involved in the accident were badly hurt.

Note - Adjectives generally describe nouns, so even if you use the word "bad" following a verb in a sentence, if it's meant to describe the thing itself, then use the adjective. "Bad" here means the same as "rotten," "rancid," or "stinky," all of which are adjectives. For example, "She had a bad taste in her mouth after eating the bad apple."

It can also operate under the pretense of being evil, of low quality, damaged, or undesirable. For example, "The writer had a bad back from sitting in a bad chair." If you can replace "bad" with another adjective and still have a sentence that makes sense, then you know that "bad" was the correct choice.

Adverbs often describe the manner in which something is done. To say "your feet smell badly" is to say that your feet are inhaling through the nose and perceiving odors, and that they're going about it all wrong.

Breath vs. Breathe

Breath (noun) - air taken into the lungs and then let out

  • Take a deep breath.

Breathe (verb) - to inhale and exhale

  • Just calm down and breathe.

One way to differentiate between the two is to remember that the noun, breath, is pronounced with an EH vowel sound, as in "bed." Meanwhile, breathe is pronounced with an EE vowel sound, as in "sheen."

Buck naked is a phrase that also means to be naked and without clothing.
