Difference between electron affinity and electronegativity?

Like the title says, can somebody explain the difference between electron affinity and electronegativity?

Electron affinity is the likelihood of an atom gaining an electron, while electronegativity is the tendency of an atom to attract electrons.

electron affinity is the ionization energy of the negative ion of an element. it's measured by giving an electron to said atom and then measuring how much energy is required to take it off. sometimes, this energy is positive, as in the case of noble gases, as the atom being so stable does not want this extra electron and pushes it off kinetic energy coming with it.

electronegativity is how much an atom is going to pull electrons to itself when in a covalent bond with another atom. this is only for nonmetals as ionic and metallic bonds do not correspond to electronegativity.

Electron affinity is the amount of energy released when electrons are added to a gas phase atom and electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself.
