Gathering of the White Council

[Legolas]

ósanwe 'communication or interchange of thought'. Apparently composed of the prefix o- "used in words describing the meeting, junction, or union of two things" (WJ:367 s.v. *WO) + sanwe (q.v.).

It seems to me that ósanwe might not include the ability to relay the same thought to several different minds. Perhaps it does allow that, but tires out the person's mind. We're not given an entire roster of the White Council - did it include men and/or dwarves? It's possible that they didn't have the ability to transmit thoughts - only receive them blessed with that ability. Is it also possible that were not aware of it? Did they have the strength of mind and thought to do it?

It'd also be more difficult when everyone started talking at once.
