Further guidance
Core difference
Use the documented noun/adjective form for the thing, result, event, or modifier; use the spaced form when the expression functions as a verb or predicate.
Fast Test
Ask what job the expression is doing in the sentence. A noun/adjective form may be closed or hyphenated by dictionary convention; a verb or predicate normally keeps the words separate.
Variant Boundary
The closed form is the noun/adjective; the two-word form belongs to the predicate “be left over.”
