The electron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.
For example, when a neutral chlorine atom in the gaseous form picks up an electron to form a Cl- ion, it releases an energy of 349 kJ/mol or 3.6 eV/atom. It is said to have an electron affinity of -349 kJ/mol and this large number indicates that it forms a stable negative ion.

The word itself answers what you ask.
Actually it is the energy released when we pump in an electron in an atom.
Normally the nucleus was stable but suddenly by the incoming electron at first it opposes but when we put it in the PE of The system increases and so energy is released and we measure this energy to estimate the value of the Electron Affinity.

1st electron affinity is the energy released when a single atom gains an electron to form a singly charged ion. Respective electron affinities may require energy instead of releasing energy as this energy is required to overcome electrostatic electronic repulsion in the ion. This is no simple word as it is likely to be incomplete.

it is the energy released when a neutral atom accepts an electron to form a gaseous anion

It is ability of an element to gain electron or draw electron to itself. it high in electronegative elements than electro-postive ones.
