sobriquet
noun
a person’s nickname
Typically a sobriquet is a name given to person for his deeds, though it can sometimes be assumed by the individual himself. Sobriquets are quite pervasive in the world of sports and sometimes you will notice sports journalists in a hurry to unleash a sobriquet and they secretly dream of their concoction sticking in the minds of the masses.Good sobriquets however are probably created after some data is available about the specialness of the character.Tagore was not given the sobriquet of “Gurdev” overnight , Mohandas karamchand Gandhi did not become the “Mahatma” in southafrica, neither did the charisma of ” Netajee” .Sobriquets stick because they capture the essence of the person and such as go on to sometimes overshadow the name itself.
Sobriquets are slightly different from nicknames.
nickname
noun
a familiar or humorous name given to a person or thing instead of or as well as the real name.
verb
give a nickname to; call by a nickname : his fraternity brothers nicknamed him “The Bird” because of his skydiving skills.
A sobriquet carries much more power than a nickname , since sobriquet more often than not refers to the acceptance of it amongst the masses rather than just friends, families and colleagues. So Michael jackson perhaps was a child was called mitch but to the people all over the world he was ” King of Pop”. Another distinction is the way a city can have a sobriquet and not a nickname. Udaipur’s Sobriquet is “City of Lakes” , “The pink city” is not a nick name for Jaipur.
