Enthalpy is basically the amount of energy exchanged by a system as heat (and/or internal energy) during a process.
Ionization Enthalpy (Energy) is the amount of energy required to ionise one mole of isolated atoms in the gaseous state. It gives the relative ease with which one may ionise a substance (i.e remove electrons from it to produce positive ions).
Electron Gain Enthalpy is the energy released when one mole of electron are added to gaseous atoms of an element.
Electron Affinity is the same as Electron Gain Enthalpy but viewed as the energy supplied to the surroundings rather than that released by the atoms. Hence its sign is opposite from the latter.
Both of these describe the ease with which the an electron can be added to the atoms of an element. Remember that ionisation enthalpy is the energy supplied taking the system as the element and electron affinity is the energy supplied to the surroundings.

Answer:
Electron gain enthalpy
When an electron is added to an isolated gaseous atom to form the negative ion an amount of energy is released during the process which is known as electron gain enthalpy of the atom. While adding the electron energy can either be release or absorbed thus it can be exothermic or endothermic process.
Ionization enthalpy
The minimum amount of energy required to remove an electron from the gaseous state of an atom is known as its ionization enthalpy. Since energy is absorbed by the atom during the process so it is a endothermic reaction.
