Lime – Meaning, Definition, Synonyms and Antonyms
Lime is used as a noun in English for (1) a small green citrus fruit with a tart flavor and (2) an industrial substance made from limestone that’s used in construction, agriculture, and water treatment.
Meaning:
As a fruit, lime is a small, green citrus used for cooking, drinks, and garnishes. Its juice is known for a sharp, tangy taste that brightens many recipes. As a material, lime can mean calcium oxide (quicklime) or calcium hydroxide (slaked lime), produced from limestone and used in building materials, soil conditioning, and water purification.
Definition:
Lime (fruit): a type of citrus fruit, typically smaller than a lemon, usually green when ripe or greenish-yellow depending on variety. The fruit is valued for its zest and juice, which add acidity to foods and beverages.
Lime (chemical/material): a substance derived from limestone. Limestone is heated to produce quicklime (calcium oxide). When quicklime is mixed with water, it forms slaked lime (calcium hydroxide). In real-world use, lime helps neutralize acidic conditions, supports soil stabilization, and assists with removing impurities during water treatment.
In everyday writing, you’ll often see the fruit sense in food contexts, while the material sense appears in agriculture, engineering, and environmental topics.
