A collocation is a combination of words that are often used together. For example when talking about the rain, you talk about heavy rain (= a lot of rain) or light rain (= a few small drops of rain).



The Thesaurus offers real support for students who want to expand their vocabulary and improve their writing. There are thousands of synonyms listed, and the thesaurus boxes explain the difference between terms that have similar meanings so that learners can find the most appropriate words for what they want to say.



Extensive vocabulary means fluency in reading comprehension, which in turn strongly relates to overall academic success.

The Study Centre offers practice to help students expand their vocabulary and use words correctly together.
