I saw this in an email message.

Problem:
The writer used an adjective where a prepositional phrase was required.

Explanation:
The writer of the email message was trying to say that a fund-raising campaign was in progress.

The word “underway” — spelled U-N-D-E-R-W-A-Y — is an adjective that means “occurring while under way”, with a space between “under” and “way”.

An example of proper use of the adjective “underway” is “The underway activities on the space shuttle include checking the toilets and watching the ants in the ant farm.”

The adjective “underway” is derived from the prepositional phrase “under way” — spelled U-N-D-E-R-SPACE-W-A-Y — which means “in progress”.

This gives us the solution.

Solution:
“The fund-raising campaign is under way!”
