Semantic Notes
"Fill-in" as a noun is hyphenated, unlike the phrasal verb "fill in." It primarily denotes a person or an act of substitution/completion.
Dialectal Variation
British vs American Usage
Differences
Both varieties use the term similarly. The compound noun 'fill-in' is standard in both. The phrasal verb 'fill in' (e.g., fill in a form) is more common in British English, where American English might prefer 'fill out' for forms.
Connotations
Neutral connotation for a temporary role. Can imply a lesser or makeshift status in some contexts.
Frequency
Common in both varieties, but perhaps slightly more frequent in American English in work contexts (e.g., 'She's a fill-in for the manager').
