lavatory

lavatory: [14] The notion of ‘washing’ was represented in prehistoric Indo-European by *lou-, which produced Greek loúein ‘wash’, English lather, and Latin lavāre ‘wash’. This last has been a fruitful source of English words, not all of them as obvious as lavatory, which originally meant simply ‘place or vessel for washing’ (its use for a ‘room containing a water closet’ appears to date from the 19th century).

Among its relatives are deluge [14], latrine [17] (from a contraction of Latin lavātrīna), laundry, lava [18] (from Italian lava, which originally denoted a ‘stream caused by sudden rain’), lavish [15] (from the metaphorical notion of an ‘outpouring’), and lotion [14]. And from Latin luere, the form taken on by lavāre after prefixes, we get ablution [14] and dilute [16]. Lavender [15] looks as though it should belong to the same family, but no actual connection has ever been demonstrated.
