What is the conditional clause of not cool enough for a

The phrase "not cool enough for a" is incomplete and doesn't form a conditional clause.

To create a conditional clause, you need a condition and a consequence.

Here's how you can make it a conditional clause:

* Add a condition: "If you are not cool enough for a..."

* Add a consequence: "then you won't be invited to the party."

Complete Conditional Clause:

"If you are not cool enough for a party, then you won't be invited."

This example shows the condition (being cool enough for a party) and the consequence (not being invited).
