Definition

Not able to reach a final state or conclusion, often used in the context of grammar or programming to describe a type of symbol that can be replaced by other symbols or sequences.

Example

In formal grammar, a nonterminal symbol can be replaced by other symbols, unlike terminal symbols which cannot be further replaced.

Conversation

Did you understand the concept of a nonterminal in our coding class?

I think so, but it's a bit confusing at times.

Yeah, it took me a while to wrap my head around it too.

Once you get the hang of it, the nonterminal ideas start making more sense.

Root Explanation

Nonterminal → It is formed from "non-" (meaning not) and "terminal" (from Latin "terminalis", meaning relating to a boundary or end). The word "nonterminal" refers to something that is not at the end or boundary, often used in contexts like grammar or computing to describe elements that do not signify a final state.

Memory Tip

Think of 'non-' meaning 'not' and 'terminal' relating to an 'end' — so nonterminal means something that is not at the end.
