The book I'm reading describes Ens$_V$ as:
Where $V$ is any set of sets, the category with objects all $X \in V$, and arrows all functions $X \rightarrow Y$, with the usual function composition.
- What does the name Ens$_V$ come from?
- What is it short for?
- How do you refer to it in speech?
It's short for "Ensemble" which is French for "set". I guess you can pronounce it as is natural for you, but just in case, the French pronunciation goes [ɑ̃sɑ̃bl], where [ɑ̃] can be found in the more well-known words "an" (year), "jambe" (leg), "sang" (blood), "temps" (time).
