This idea was suggested to me by Simon Cosgriff of Curtin University.
Take the word proximity. Have the learner do a Google search of, say, “proximity CNN.” They then look at the first six articles and note down as many collocations with proximity as possible.
A screenshot of the first three results alone yields close proximity, proximity to and proximity of X to:
The learner could then try and formulate their own sentences using the collocations.
