A white caustic alkaline substance consisting of calcium oxide, which is obtained by heating limestone and which combines with water with the production of much heat; quicklime.

Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.

Birdlime.

A silvery, moderately hard alkaline-earth metal that constitutes approximately 3.6 percent of the earth's crust and is a basic component of most animals and plants. It occurs naturally in limestone, gypsum, and fluorite, and its compounds are used to make plaster, quicklime, Portland cement, and metallurgic and electronic materials. Atomic number 20; atomic weight 40.08; melting point 842°C; boiling point 1,484°C; specific gravity 1.54; valence 2. See Periodic Table.

A rounded citrus fruit similar to a lemon but greener, smaller, and with a distinctive acid flavour

The chemical element (Symbol Ca), with an atomic number 20. It is a soft, silvery-white alkaline earth metal which occurs naturally as carbonate in limestone and as silicate in many rocks.

The evergreen citrus tree which produces limes, widely cultivated in warm climates.

(countable) An atom of this element.

A bright light green colour like that of a lime

An elementary substance; a metal which combined with oxygen forms lime. It is of a pale yellow color, tenacious, and malleable. It is a member of the alkaline earth group of elements. Atomic weight 40. Symbol Ca.

A deciduous tree with heart-shaped leaves and fragrant yellowish blossom, native to north temperate regions. The pale timber is used for carving and inexpensive furniture.

A white metallic element that burns with a brilliant light; the fifth most abundant element in the earth's crust; an important component of most plants and animals

An informal social gathering characterized by semi-ritualized talking.

Treat (soil or water) with lime to reduce acidity and improve fertility or oxygen levels

Catch (a bird) with birdlime

Sit or stand around talking with others

Any of several evergreen trees or shrubs of the genus Citrus having edible green or greenish-yellow fruit, especially the Mexican lime and the Persian lime.

The fruit of any of these plants, having a pulpy interior and usually acid juice.

See linden.

See calcium oxide.

Any of various mineral and industrial forms of calcium oxide differing chiefly in water content and percentage of constituents such as magnesia, silica, alumina, and iron.

Birdlime.

To treat with lime.

To smear with birdlime.

To catch or snare with or as if with birdlime.

(chemistry) Any inorganic material containing calcium, usually calcium oxide (quicklime) or calcium hydroxide (slaked lime).

(poetic) Any gluey or adhesive substance; something which traps or captures someone; sometimes a synonym for birdlime.

(theatre) A spotlight.

A deciduous tree of the genus Tilia, especially Tilia × europaea; the linden tree.

The wood of this tree.

Any of several green citrus fruit, somewhat smaller and sharper-tasting than a lemon.

Any of the trees that bear limes, especially Key lime, Citrus aurantiifolia.

(uncountable) A brilliant, sometimes yellowish, green colour associated with the fruits of a lime tree.

A casual gathering to socialize.

(transitive) To treat with calcium hydroxide or calcium oxide (lime).

(transitive) To smear with birdlime.

(rare) To ensnare, catch, entrap.

(transitive) To apply limewash.

To hang out/socialize in an informal, relaxed environment, especially with friends, for example at a party or on the beach.

Containing lime or lime juice.

Having the aroma or flavor of lime.

Lime-green.

A thong by which a dog is led; a leash.

The linden tree. See Linden.

The fruit of the Citrus aurantifolia, allied to the lemon, but greener in color; also, the tree which bears it.

The color of the lime{1}, a yellowish-green.

Birdlime.

Oxide of calcium, CaO; the white or gray, caustic substance, usually called quicklime, obtained by calcining limestone or shells, the heat driving off carbon dioxide and leaving lime. It develops great heat when treated with water, forming slaked lime, and is an essential ingredient of cement, plastering, mortar, etc.

To smear with a viscous substance, as birdlime.

To entangle; to insnare.

To treat with lime, or oxide or hydrate of calcium; to manure with lime; as, to lime hides for removing the hair; to lime sails in order to whiten them; to lime the lawn to decrease acidity of the soil.

To cement.

Having a yellowish-green color like that of the lime (the fruit).

A caustic substance produced by heating limestone

A white crystalline oxide used in the production of calcium hydroxide

A sticky adhesive that is smeared on small branches to capture small birds

Any of various related trees bearing limes

Any of various deciduous trees of the genus Tilia with heart-shaped leaves and drooping cymose clusters of yellowish often fragrant flowers; several yield valuable timber

The green acidic fruit of any of various lime trees

Spread birdlime on branches to catch birds

Cover with lime so as to induce growth;

Calcium is a chemical element essential for bone health, muscle function, and numerous industrial processes.

Lime, or calcium oxide, is a compound used in building materials, agriculture, and environmental applications.

Calcium is vital for building strong bones and teeth, and it's crucial in muscle function and nerve transmission.

The construction, agriculture, and environmental sectors frequently use lime in various applications.

Lime is used to make mortar and plaster, contributing to the durability of buildings.

Yes, lime can improve soil health by adjusting pH levels, making nutrients more available to plants.

Lime is produced by heating limestone (calcium carbonate) in a kiln, a process that drives off carbon dioxide to leave calcium oxide.

Calcium ions play a key role in biological processes, including blood clotting, muscle contractions, and nerve functions.

Calcium ions trigger muscle contractions by interacting with proteins in muscle cells.

Calcium supplements can be beneficial, especially for individuals at risk of bone-related conditions.

Lime can be environmentally beneficial, particularly in water treatment and pollution control.

Calcium is found in various minerals, such as limestone, gypsum, and fluorite, and is abundant in the Earth's crust.

Dairy products, leafy greens, and fortified foods are high in calcium.

Yes, lime is used in water treatment processes to adjust pH and remove impurities.

No, lime (calcium oxide) is produced from limestone (calcium carbonate) through a heating process that removes carbon dioxide.
