Classical is used for established artistic traditions and for things connected with ancient Greek and Roman culture.

Both words come from child, but their usual tone is different.

Childlike often highlights qualities associated positively with children, such as openness, enthusiasm, innocence, or trust.

Childish can simply mean typical of a child, but when it describes an adult’s behavior, it is usually disapproving and means immature or silly.

So:

• childlike curiosity = innocent or enthusiastic curiosity

Continual and continuous both describe things that continue, but there is a useful difference in many contexts.

Continual often describes something that happens repeatedly, possibly with breaks between occurrences.

Continuous commonly describes something continuing without a break or interruption.

A simple way to remember the usual distinction is:

• continual interruptions = interruptions that keep happening
• continuous noise = noise that does not stop

The meanings can overlap in some contexts, so this is a useful tendency rather than an absolute rule.

Complementary or Complimentary?

Only one letter changes, but the meanings are very different.

Complementary describes things that work especially well together because each adds something useful to the other.

Their complementary skills made them an effective team.

Complimentary has two common meanings. It can mean expressing praise.

The reviewer was highly complimentary about her performance.

It can also mean provided free of charge.

So:

• complementary skills = different skills that work especially well together
• complimentary remarks = words of praise
• complimentary ticket = a free ticket

Credible or Credulous?

Both words relate to believing, but they describe different sides of the situation.

Credible describes something or someone believable or convincing.

The witness gave a credible account of what happened.

Credulous is a formal adjective for someone too willing to believe what they are told.

The scam was designed to deceive credulous buyers.

So:

• a credible story is believable
