What does express mean?
Express is one of English's most versatile words, serving as a verb, adjective, and noun. As a verb, it means to convey a thought, emotion, or idea through language, gesture, art, or another medium — people express opinions, feelings, and gratitude. It can also mean to represent something symbolically, as when mathematicians express quantities as equations, or even to press out a liquid, as in expressing juice from fruit. As an adjective, express describes anything that travels or operates directly for a particular purpose without intermediate steps: an express train skips smaller stations, an express letter is delivered with priority, and an express lane speeds shoppers on their way. As a noun it denotes a fast train or courier service. Derived from Latin exprimere, meaning to press out, the word carries a vivid underlying image: thoughts being pressed outward from mind into the world. Its derivatives include expression, expressive, and expressly.
To convey a thought, feeling, or idea in words, gestures, art, or another medium of communication; also to represent something symbolically, or to squeeze out a substance under pressure.
"She used poetry to express emotions she could not say aloud."
In scientific and mathematical writing, 'express X as Y' is the standard formulation for symbolic representation.
Operating directly and without intermediate stops, or sent or done with speed for a specific purpose.
"They caught the express elevator straight to the top floor."
A fast train, bus, or delivery service that makes few intermediate stops; more broadly, any rapid dispatch or courier service.
"The overnight express arrived in Chicago by morning."
Applies only to the noun form, referring to multiple express trains or delivery services; rare outside discussions of transport or shipping.
"Both expresses departed from platform four at noon."
The word 'express' literally means to 'press out' — the same Latin root that gives us 'impress' and 'depress' — so when you express yourself, you're squeezing your inner thoughts out into the world.

Etymology of express
Express derives from Latin exprimere, formed from ex- ('out') plus premere ('to press'), literally meaning to press out. It entered Middle English via Old French around the late medieval period, initially carrying the sense of pressing or squeezing out, and later developed its meanings of conveying ideas and moving rapidly without stops. Cognates sharing the same Latin root include impress, depress, compress, and pressure itself.
