Endothermic - A chemical reaction in which more energy is needed to break the chemical bonds than is given off when they are remade. So its takes in energy giving a cooling effect.
Exothermic - A chemical reaction in which more energy is used making the bonds than breaking them, so the excess energy is given off. This gives a warming effect.

In the physical sciences, the word endothermic, in contrast to the word exothermic, describes a process or reaction that absorbs energy in the form of heat. The concept is frequently applied to chemical reactions, where chemical bond energy is converted to thermal energy (heat). If the system undergoes a transformation which is both endothermic and adiabatic, i.e. adiabatic meaning that heat is generated internally but no heat is given off to the surroundings, its temperature decreases

in chemistry language...we use the words exothermic reaction and endothermic reaction...
so the meaning of endothermic is to take in heat and the meaning of exothermic is to give out heat...

ENDOTHERMIC: 1. Chemistry (of a reaction) accompanied by the
absorption of heat.
2. Zoology (of an animal) dependent on the
internal generation of heat.
EXOTHERMIC: 1. Chemistry (of a reaction) accompanied by the
release of heat. The opposite of endothermic.

these terms refer to chemical reactions. an exothermic reaction is one which is produced with heat emission and an endothermic reaction is produced with heat absorption

endothermic: adjective :- Chemistry : of or relating to a chemical reaction in which heat is absorbed.
exothermic: adjective :- Chemistry : of or relating to a chemical reaction in which heat is produced.
