How to Use -ful Words in Real Life

Most -ful words are positive. You can use them in both formal and informal situations, but some are more common in conversation than in writing.

For example, in a work email you might write: “Thank you for your helpful advice.” In a text to a friend, you might say: “That was a wonderful movie!”

Better (more professional): “Your report was helpful and useful.”
