"Blend of Juan and Luis"
The name Juanluis is commonly a male name from the "Spanish" origin.
Juanluis is a compound of the Spanish given names Juan and Luis, the same combination normally written as two words, Juan Luis. Juan is the Spanish form of John and Luis is the Spanish form of Louis, so the name adds no meaning of its own beyond the two names it joins. In United States birth records it is written as a single word.
The pronunciation of Juanluis is wahn-LOO-ees.
