1132 (''legʷh-'')
''Lambrus'' corresponds to Greek ἐλαφρός, meaning 'light (in weight), quick, nimble' ('leicht, flink' in German) and is related to Illyrian ''lembus'' (*''lengʷho-s'') 'light vehicle' ('leichtes Fahrzeug' in German), whence also Greek λέμβος. Pokorny cites Krahe, ''Gymnasium'' 59 (1952), p. 79.
