luimë

flood

luimë noun "flood" (VT48:23, 30; the additional glosses "floodwater, flooded land" were struck out, VT48:30), "flood, high tide" (VT48:24, 30). According to VT48:30, partially illegible glosses in Tolkien's manuscript may also suggest that luimë can be used for any tide, or for the spring tide (the maximum tide just after a new or full moon).
