Collocate is a verb that is defined as words or items being set side by side. This word has been around since the early 1500s.
Colocate is a verb that means to place two or more items closely together, sometimes in order to use a shared resource. An alternative spelling includes a hyphen, co-locate, though at least one prominent dictionary did not list it. The hyphenated spelling is the first listing in some European dictionaries, with no alternative listed as well. The varied definitions isn’t too surprising. This word has only been around since the sixties and hyphens are almost always problematic.
In actual usage, we found that the hyphen spelling is found in and outside the United States and is, in fact, the more preferred form.
The noun form is colocation or co-location.
