Definition

In a manner that involves hypergolic reactions, which are chemical reactions that ignite spontaneously upon contact between two substances.

Example

The rocket engines operated hypergolically, ensuring immediate ignition when the fuel and oxidizer met.

Conversation

Did you notice how the rocket launches were done hypergolically?

Yeah, it was fascinating to see how quickly they ignited!

I wonder if that's the most efficient way to launch them.

It seems like it, especially for those rapid missions.

Root Explanation

Hypergolically → It is formed from "hyper-" (meaning over or excessive) and "gole" (from Greek "gole", meaning to throw). The word refers to a method of propulsion in which fuel and oxidizer ignite spontaneously upon contact, thus representing an excessive or over-the-top reaction.

Memory Tip

Think of 'hyper-' meaning excessive and 'gole' relating to throwing — this helps you remember that hypergolically refers to a reaction that occurs spontaneously and dramatically.
