What does expo mean?
An expo is a large-scale public exhibition, typically organized around an industry, theme, or occasion, where companies, institutions, and creators gather to display their latest products, technologies, or ideas to visitors. The word is a clipped form of 'exposition' and is used informally but widely in both British and American English, especially in commercial contexts: trade expos, auto expos, food expos, and tech expos are fixtures of the modern business calendar. On the grandest scale, a World Expo is an international exhibition of the kind historically known as a world's fair — events that have introduced landmarks like the Eiffel Tower and inventions such as the television to global audiences. Commonly used attributively ('expo hall', 'expo floor'), the word carries connotations of scale, novelty, networking, and spectacle, making it the go-to term for events built around showing things off.

Etymology of expo
'Expo' arose in the mid-20th century as a clipping of 'exposition', which entered English via French from Latin 'expositio', meaning 'a setting forth' — from 'exponere' (to set out or display), itself formed from 'ex-' (out) plus 'ponere' (to place). The same Latin root gives English related words such as 'expose', 'exposure', and 'component'. The shortened form gained particular prominence through its use in the names of major international exhibitions, notably Expo 58 in Brussels and Expo 67 in Montreal, which cemented it as a standalone word.
How expo is actually used
Informal but fully standard in both British and American English; in formal writing 'exhibition' or 'exposition' may be preferred. Frequently used attributively as a modifier, as in 'expo hall', 'expo floor', and 'expo center'.
