How can you use compound word in the fire?

You can't use a compound word *in* the fire. "In the fire" implies a physical location within the flames. Compound words are just combinations of two or more words, and they exist as language, not physical objects.

Perhaps you're asking about a different concept? Could you clarify what you mean?

For example, maybe you're interested in:

* Compound words related to fire: like "fireplace," "firefighter," or "firestorm."

* Using compound words to describe fire: "The blaze was a fiery inferno."

* Something else entirely?
