[Word-ology] Incredible=In+Cred+Ible

💡Time for [Word-ology] again, a column making English learning easier!💡

Before today’s learning, let’s check the answers to the last episode.


Definition: to swell or make sth swell because of pressure from inside


Definition: expressing a strong opinion that people are likely to disagree with

The Latin root word cred means “believe. Today, we are going to explore some English words using the root “cred“.

The word “incredible” consists of three etyma: “in“, “cred” and “ible“. The prefix in- means “not“, and the suffix -ible is a mark of the adjective, which means “capable of“, just like the suffix -able.

Therefore, something credible is “capable of being believed or trusted“, and if something incredible happens it can hardly be “believed“, in other words, it is very unusual or surprising, and you cannot believe it is really true.


If you are given credit, you are allowed to pay for goods or services several weeks or months after you have received them. When a bank offers you a credit card, it “believes” that you have the financial ability to handle the amount you charge on it. The amount of money, or credit line, that the bank gives you is the amount of money it “believes” you’ll be able to handle financially, and “believes” that you can afford to pay back.

Now it’s your time to figure out the meanings of the following words!

credulous=cred-[believe]+ulous-[adj. tending to do or characterized by]

Example: Mary is so credulous that she may easily accept any excuse you make.

discredit=dis-[stop people from doing something]+cred-[believe]+it

Example: The photos were deliberately taken to discredit the President.

That’s all for [Word-ology] today!
