What if you could understand a word you've never seen before? By learning common prefixes and suffixes, you can decode meaning on the fly.
This is especially useful in the TEF/TCF Reading Section, where you'll encounter academic or technical vocabulary. Instead of panicking, you can deconstruct.

Think of prefixes and suffixes as your vocabulary "cheat codes". Memorize the top 10 of each, and suddenly a vast swath of French becomes transparent. This isn't about learning words one by one; it's about learning the building blocks.
