Definition

The ability of a substance to be infused or poured in, or the difficulty of a substance to be melted or dissolved.

Example

The infusibility of certain metals makes them ideal for high-temperature applications.

Conversation

Did you know that some materials have high infusibility?

Really? I didn't know that; what does it mean exactly?

It means they are difficult to melt or dissolve, like certain metals.

That makes sense! I guess that’s why they’re used in construction.

Root Explanation

Infusibility → It is formed from "in-" (meaning not) and "fusibilis" (from Latin "fundere", meaning to pour). The word describes the quality of not being able to be poured or melted easily.

Memory Tip

Think of something that is 'not' ('in-') able to be 'poured' ('fusibilis') — that's why infusibility means it cannot be easily melted or poured.
