§ Lameduin (of Lamedon) with tributaries Serni, Kelos (TI:312)
For these see VT42:11,17. Later, Lameduin does not occur; but it appears to be partly or completely interpretable, containing duin ’river’ (DUI-, VT45:11) and perhaps some derivative of LAM-, which produces words for ’sound’ and ’echo’ in The Etymologies, hence Lameduin < *lamme-duin *’echoing river’.
