laiwa

adjective. sickly, sick, ill

An adjective appearing as ᴹQ. laiwa “sickly, sick, ill” in The Etymologies of the 1930s derived from primitive ᴹ✶slaiwā under the root ᴹ√SLIW “sickly” (Ety/SLIW). The ancient initial sl became voiceless hl, which was then voiced to l as was generally the case in The Etymologies.

Neo-Quenya: In Tolkien’s later writing, he usually retained hl- in spelling if not pronunciation; see the entry on how initial voiceless nasals and liquids were voiced for discussion. As such, most Neo-Quenya writers adapt this word as ᴺQ. hlaiwa.

Conceptual Development: The Qenya Lexicon of the 1910s had the word ᴱQ. leuke (leuki-) “sick, ill; pallid, wan” under the similar but earlier root ᴱ√LEẆE (QL/53).
