What is the meaning of the name "Sulub"

[MaraaQ]

Not sure if this is the right thread for this but thought someone more knowledgeable could answer. From what I know its a name of Somali origin and the name is quite rare to see nowadays. I've been wondering what it meant for awhile however information on it is hard to come by. I've heard meanings like smooth, discipline, handsome etc. They're all over the place and I was hoping to see if anyone has knowledge on this.

In its noun form, I think 'sulub' means solid, smooth, and without blemish, as in 'ul sulub ah', for instance a stick after bark and branches had been stripped and flushed. If you have done any carpentry or woodwork, it would make better sense.

It might be of the same root as the Arabic word ' صُلْب '

Just a thought.

Just looked up in a dictionary, and this is what it says.
