What is the meaning of reagent?
Definition of reagent : a substance used (as in detecting or measuring a component, in preparing a product, or in developing photographs) because of its chemical or biological activity chemistry : a substance that is used to test for the presence of another substance by causing a chemical reaction with it
Can a substance be a reagent without having the word reagent in it?
However, a substance may be used as a reagent without having the word "reagent" in its name. The term reagent is often used in place of reactant, however, a reagent may not necessarily be consumed in a reaction as a reactant would be. For example, a catalyst is a reagent but is not consumed in the reaction.

Products are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state. This process results in the consumption of the reactants.
Are reagents and reactants the same thing?
A reactant is a substrate in a reaction, whereas a reagent is a catalyst. Regents can also be limiting. Limiting reagents stop a chemical reaction when they are used up. The chemical reaction relies on the reagent to continue the reaction and stops when there is no more substance.
