show case (showcase)

Choose 'showcase' (one word) when you mean an event, a platform/display, or the verb "to showcase." Use 'show case' (two words) only when you literally mean a case that belongs to a show-a rare, literal sense.

Below: a short rule, tight grammar notes, quick rewrites you can paste, lots of wrong→right pairs, and realistic work, school, and casual examples so you can fix sentences fast.

Short answer

Use 'showcase' (one word) for events, displays, and the verb 'to showcase'. Use 'show case' (two words) only for a literal case used in a show. When in doubt, default to 'showcase'.

showcase (one word) - noun: event or display; noun: a glass/display case; verb: to display or highlight.
show case (two words) - literal noun phrase: a case used in a show (rare).
Avoid the hyphenated form 'show-case' in modern usage.

Core explanation: meaning decides the form

'Showcase' is the standard, dictionary-listed form when you mean an event or the act of displaying-e.g., a product showcase or to showcase talent. It also names a physical display (a glass or enclosed case).

'Show case' splits the words and only works when 'show' and 'case' are independent-when you truly mean a case belonging to a show. Most writers never need that literal meaning; they mean 'showcase'.

If you mean an event, display, or the act of displaying → use showcase.
If you really mean a physical case used in a show → rewrite as the case used in the show or a case for the touring production for clarity.

Right: The design team created a digital showcase for the new features.
Wrong: They placed the trophies in the show case by the judges' table. (If you mean the physical container, rephrase.)
Right: They placed the trophies in the showcase by the judges' table.

Spacing and hyphenation (short)

Compound words often join over time. For the display/event/verb senses, showcase is the accepted closed form. The hyphen 'show-case' is outdated and unnecessary.

Search your draft for 'show case' (with a space). Most hits should become 'showcase'.
Only keep the spaced form when the literal meaning applies; otherwise replace it.

Wrong: We will show-case the finalists tomorrow.
Right: We will showcase the finalists tomorrow.

Grammar: noun, verb, and possessives

Showcase functions as both noun and verb. As a noun it names an event or a physical display; as a verb it means to display or highlight.

Possessives and modifiers work naturally with the closed form. If a possessive sounds awkward, rephrase: instead of "the product's showcase," say "the product showcase" or "the showcase of products."

Noun (event): an artist showcase, the product showcase.
Noun (physical): a glass showcase (display case).
Verb: to showcase new features, we showcased her work.
Rephrase awkward possessives: the band's showcase → the showcase featuring the band.

Usage: Verb: The festival will showcase independent films.
Usage: Noun (physical): The museum's newest showcase holds medieval coins.
Usage: Awkward: The product's showcase was crowded. Better: The product showcase was crowded.

Real usage: copyable examples for work, school, and casual contexts

These natural examples all use showcase as the standard form for each context.
