The best definition u can get is from the bible. Its
in 1st Corinthians 13:4-8
4Love is patient, love is kind. It
does not envy, it does not boast, it is not proud. 5It is not rude, it is not self-seeking, it is not easily
angered, it keeps no record of wrongs. 6Love
does not delight in evil but rejoices with the truth. 7It always protects, always trusts, always hopes, always
perseveres. 8Love never fails.
If you want to know more in depth you can go try reading this
book call 5language of love. All the best =)
