collocator
noun1
A word which often or regularly collocates with another word.
- The collocator is familiar to the speaker of English who is not aware of its idiomaticity, while for the foreign language learner it is unpredictable, because his/her mother tongue privileges another word.2014, Rufus Gouws, Dictionaries.
