What is the meaning of 'allusion' and 'illusion' respectively?

An indirect reference, A false idea

The answer is ☀ An indirect reference, A false idea.

• Allusion is a reference to something that is already known, but not explicitly mentioned. It is often used in literature and art to add depth and meaning.
• Illusion is a false idea or perception. It is often caused by the misinterpretation of a sensory experience.

The two words are often confused because they sound similar. However, they have different meanings and are used in different contexts.

Allusion is used to make a reference to something that is already known. For example, you might say "The painting was an allusion to the Greek myth of Narcissus" or "The poem made an allusion to the American Civil War."

Illusion is used to describe a false idea or perception. For example, you might say "The magician created an illusion of a floating woman" or "The woman was under the illusion that she was still young."

The other options are incorrect. Dream is not a synonym for either allusion or illusion.
