A word for “bedchamber” in The Etymologies from around 1937, a combination of ᴹQ. kaima “bed” and ᴹQ. sambe “chamber” (Ety/KAY, STAB). Its plural kaimasambi indicates a stem form of kaimasamb-.
Conceptual Development: This word first appeared as ᴱQ. {kaitosambe >>} kaimasambe “bed-room” in the Qenya Lexicon of the 1910s (QL/46). It reappeared as kaimasan (kaimasamb-) “bed-chamber” in the Early Qenya Grammar of the 1920s (PE14/42, 71) and appeared as kaimasan with plural kaimasambi in the English-Qenya Dictionary of this same period (PE15/70). It appeared again as kaimasan (kaimasamb-) in the Declension of Nouns of the early 1930s (PE21/17, 37). At each earlier stage it had essentially the same derivation as in The Etymologies, so the word was fairly well established.
A noun for “bed” in The Etymologies from around 1937 under the root ᴹ√KAY “lie down” (Ety/KAY).
Conceptual Development: In the Qenya Lexicon of the 1910s, ᴱQ. kaima was glossed “couch” under the early root ᴱ√KAYA “lie, rest; dwell” (QL/46) and ᴱQ. kamba was glossed “bed” under the early root ᴱ√KAMA “lie down” (QL/44). However, ᴱQ. kaima was “bed” in the English-Qenya Dictionary of the 1920s (PE15/70). The form kaimas appeared unglossed in The Feanorian Alphabet of the 1930s (PE22/19), possibly an inflected form of kaima “bed”.
