Affinity, in etymology affinity is the opposite of infinity . These two words have the same root coming from the Latin: finis = end. “Affinity” meaning is near to the “finis” e.g. close to the “zero point” in a before assumed space.

On the other hand, from the Latin, affinis = connected with, having things in common, and it is utilised to interpret the effective possibility that some substances can or cannot mix together, in terms of sympathies and antipathies.

Also, it can mean a natural attraction of feeling or kinship. A relationship by marriage.
