The word "express" generally means to convey or communicate thoughts, feelings, or ideas effectively and clearly. It can refer to the way someone demonstrates their emotions, articulates their opinions, or showcases creativity. In a broader sense, it can also mean to make something known or visible.
The word "express" originates from the Latin "expressus," which is the past participle of "exprimere," meaning "to press out" or "to express." The prefix "ex-" means "out," and "primere" means "to press." This etymology reflects the idea of bringing something out or making it clear.
