I see your point, though the relation is likely reverse: adding an object
turns the absolute into smihut. So, you suggest that lmo is conjugated form
of lamo, and that cmo and bmo lost their protoform camo, bamo. Possible.
The conjugated form lmo becomes essentially preposition. Its semantics
expands. The original collective plural (lamo) is occasionally employed as
emphatic for singular (lmo). Quite possible.
Why lamo, while lca? Perhaps lamo=l:hemo. I think you have a case.
