I know the meaning of mine.
My name “LJUBOMIR” is a Croatian and Serbian name, according to the website Behind the Name.
It is Љубомир in Serbian (probably this is written in Cyrillic, but I’m not sure).
LJUBOMIR is the Croatian and Serbian form of “LUBOMIR,” which in turn is the Polish form of “LUBOMÍR,” a Czech name.
The same website says LUBOMÍR “means love and peace from the Slavic elements ‘lyub’ (love) and ‘mir’ (peace).”
LJUBOMIR = love and peace
It may also mean “great love.”
Behind the Name says the Old Slavic “mer” means “great.”
