What is a generic description and why shouldn't you overuse them?

An overused generic description is one that doesn't add any specificity to your sentence.

The girl was nice.

The giraffe was very tall.

I think your idea sounds great.

These sentences are not very powerful because their exact meaning is open to interpretation. Try to find more descriptive ways to express yourself.

The girl treated everyone she met with respect.

The giraffe towered over the other giraffes.

I think your idea sounds like an excellent compromise.

You can always come up with better words to use in place of overused generic descriptions.
