#EngClass: Prefix (Revisit)

Good evening, fellas! How was your day? Did you have a good time celebrating our Independence Day? On this special day, let’s make today an even more special one, shall we? Mark today as the day we discuss Prefix!

How many of you have read our past post on prefix? If you haven’t, let me point you to it. ~> #EngClass: Prefix 

In today’s #EngClass we’ll revisit and refresh our memory on Prefixes. Or ‘awalan’ as we might call it in Bahasa Indonesia.


As the name suggests… prefix is a group of letters placed in front of a root word. Prefixes, by themselves, are not words. Can you think of any example of prefixes, fellas?


Agree [v] = to accept or support, setuju.

(Dis)agree [v] = to not accept, to differ, tidak setuju.

Other examples:

@FabioFluzao: No, I can’t. It’s IMpossible! ;))))

@betipuspah: such as stable and unstable

@MeLLDinnard: Disappear? Uncommon?

Most prefixes are added to root words without adding or omitting a letter. By adding prefix to a root word, it changes its meaning… never the part of speech.

Today, well talk about some of the most commonly used prefixes. They are: dis-, in-, im-, il-, ir-, pre-, re-, un-.
