Master the Building Blocks of English 🧱
A prefix is a letter or group of letters added to the beginning of a word to change its meaning. Think of them as "upgrades" for words! Learning just a few prefixes can instantly unlock the definitions of thousands of words.
Why learn Prefixes? 📊
A significant portion of the English vocabulary is formed by combining roots with affixes. This chart visualizes the makeup of complex words.
