Conversation

I read an article about theories that are considered untestable.

Really? What kind of theories are they talking about?

They mentioned some ideas in physics that can't be proven right or wrong.

That sounds frustrating, especially when scientists want to find answers.

Root Explanation

Untestable → It is formed from "un-" (meaning not) and "test" (from Latin "testari", meaning to witness or to prove) and "-able" (meaning capable of). The word "untestable" means not capable of being tested or proven.

Memory Tip

Think of 'not' ('un-') being added to 'test' (to prove something) and 'able' (capable of). This helps you remember that 'untestable' refers to something that cannot be proven or tested.
