Meaning & History

The first element of this name is derived from old Lithuanian gailas, which usually means "strong, potent" but has also been found to mean "sharp, jagged" as well as "angry, fierce, violent" and "miserable, sorrowful, remorseful". Also compare the modern Lithuanian noun galia meaning "power, might, force". The second element of this name is either derived from Lithuanian mantus meaning "intelligent" (see Daumantas) or from Lithuanian manta meaning "property, estate" as well as "wealth, riches, fortune".

In other words: this given name is basically the same as Mantgailas and Mantigailas, but with the name elements in different places.
