Idol, Idle, and Idyll
The words idol, idle, and idyll sound similar, but their meanings are very different.
The nounidol denotes a representation (e.g., statue, carving, figurine) of a god used as an object of worship. The word idol is often used figuratively to denote a person or object that is greatly admired, loved, or revered. For example:

A god who lets us prove his existence would just be an idol. (Dietrich Bonhoeffer)

(The verb to idolize comes from idol.)
The word idle is most commonly used as an adjective meaning lazy or work-shy. For example:

It is the working man who is the happy man. It is the idle man who is the miserable man. (Benjamin Franklin)
Idle can also mean worthless or pointless. For example:
I have no time to engage in idle gossip.
As we must account for every idle word, so must we account for every idle silence. (Benjamin Franklin)
Idle can also be used as verb meaning to take it easy, languish, or lounge around. For example:

I need to idle on the beach for a week with a good book.
When it refers to an engine, to idle means to run slowly while out of gear or detached from a load. For example:
