Explain electrophilic aromatic substitution?

Electrophilic aromatic substitution (SEAr) is an organic reaction in which an atom that is attached to an aromatic system (usually hydrogen) is replaced by an electrophile.

An electrophile is reagent that is attracted to electrons (it means electron lover!)
