Have you ever noticed how many words in English start with “pre-” or “post-”? Think about “preview,” “preschool,” “postgame,” or “postgraduate.” These little word parts appear everywhere, and they give us important clues about what a word means. But what exactly do pre and post mean? And how can you use them correctly in everyday life?
In this article, we’re going to break it down step by step. We’ll look at what “pre” means, what “post” means, how they are used, and plenty of examples you can easily understand. By the end, you’ll be able to recognize these prefixes quickly and use them with confidence.
Let’s get started.
What Do Pre and Post Mean?
To begin with, both pre and post are prefixes. A prefix is a short word part added to the beginning of another word to change its meaning.
- Pre means “before.”
- Post means “after.”
It’s really that simple! Whenever you see a word starting with pre-, you can usually think “before.” And whenever you see post-, you can usually think “after.”
Breaking Down Pre: What Does Pre Mean?
Pre comes from the Latin word prae, which means “before” or “in front of.” When we add “pre” to a word, it tells us that something happens earlier, ahead of time, or before something else.
Examples of Pre in Action:
- Preview – to look at something before it is officially shown.
- Preschool – school for children before they go to primary school.
- Prepay – to pay for something before using it.
- Preheat – to heat an oven before cooking.
Sentence Examples:
- “We watched a preview of the new movie.”
- “My daughter goes to preschool.”
- “You need to prepay for your meal at that café.”
- “Don’t forget to preheat the oven before baking.”
As you can see, “pre” always signals something happening ahead of time.
Breaking Down Post: What Does Post Mean?
Post comes from the Latin word post, which means “after” or “behind.” When we add “post” to a word, it tells us that something happens later or after something else.
Examples of Post in Action:
- Postgame – something that happens after a game.
- Postgraduate – studying after graduating from college or university.
- Postwar – the period after a war.
- Postscript (P.S.) – something written after the main part of a letter.
Sentence Examples:
- “The team had a party at a postgame celebration.”
- “She is taking a postgraduate course in medicine.”
- “Many countries struggled during the postwar years.”
- “He added a short postscript at the end of the letter.”
So whenever you see “post,” think about something that comes later.
Pre vs. Post: A Quick Comparison
It helps to compare them side by side:
- Pre-event = before the event
- Post-event = after the event
- Pre-lunch meeting = before lunch
- Post-lunch meeting = after lunch
- Pre-test jitters = nervous feelings before the test
- Post-test relief = the relaxed feeling after the test
Key takeaway:
- Pre = before
- Post = after
This is the golden rule to remember.
