I was reading about language rules, and I came across the term suppletive forms.

Oh really? What does that mean exactly?

It refers to how some words change completely instead of just adding endings, like 'good' to 'better'.

Root Explanation

Suppletive → It is formed from "suppletus" (meaning filled up or completed) and the suffix "-ive" (meaning having the nature of). The word "suppletive" refers to something that serves to fill in or complete a gap, particularly in grammar.
