The Lennox (Scottish Gaelic: Leamhnachd, pronounced [ˈʎãũnəxk]) is a region of Scotland centred on The Vale of Leven, including its great loch: Loch Lomond. The Gaelic name of the river is Leamhn, meaning the smooth stream, which anglicises to Leven (as Gaelic mh is spirantised). The surrounding area is the field of the smooth stream - Leamhnachd in Gaelic; this was originally anglicised as Levenauchen / Levenachs, then softened into Levenax / Lennax, and eventually the area was known simply as Lennox.
