Synonyms & Antonyms

Root Explanation

Instructive → It is formed from "in-" (meaning into or upon) and "struere" (meaning to build). The word "instructive" means serving to build knowledge or understanding in someone.

Memory Tip

Think of 'building knowledge' ('struere') in someone 'into' ('in-') them — that's why instructive means it helps you learn.
