Collocations and how to learn them

Collocations are important to be mindful of, and you should learn to remember them when you see or hear them.

Treat collocations as if they were single words. See them as separate blocks or chunks, and learn to strongly support rather than strongly + support.

When you hear a new phrase, make a list of other words that are similar to it.

Read as much as possible. Reading is a fantastic way to master words and collocations spontaneously and in detail.

Regularly review what you've learned. As soon as possible after discovering new collocations, practice using them in context.

Collocations can be learned in classes that are convenient for you. You may study them by subject (time, number, weather, resources, and family) or by a specific term (do something, take a gamble, take a test)

Any decent learner's dictionary will include details on collocations. You can also find advanced collocation dictionaries.
