A large pole used to support a tent, or a major production in entertainment that generates significant revenue for its creators.
The new superhero movie is considered a tentpole for the studio, expected to bring in a lot of money.
**Tentpole** → The word is formed from "tent" (from Old French *tente*, meaning a portable shelter) and "pole" (from Old English *pal*, meaning a long, slender piece of wood). A tentpole is a pole that supports a tent, providing structure and stability.
Imagine a 'portable shelter' ('tent') being held up by a 'long piece of wood' ('pole') — that's how a tentpole supports the structure.
