A noun for “roof” in The Etymologies of the 1930s under the root ᴹ√TOP “cover, roof” (Ety/TOP).
Conceptual Development: The Qenya Lexicon of the 1910s had a similar form ᴱQ. túpo “roof, cover, lid” under the early root ᴱ√TUPU (QL/95), with just the gloss “roof” in the contemporaneous Poetic and Mythological Words of Eldarissa (PME/95). It also had a couple of other unrelated words: ᴱQ. tel (teld-) “roof” and ᴱQ. telin (telimb-) “roof, covering” both derived from the early root ᴱ√TELE (QL/90).
A word for “canopy” appearing in the Declension of Nouns of the early 1930s, an elaboration of ᴹQ. telume “vault, heaven” (PE21/16). It initially had a stem form of telumeht- (PE21/16), but this was revised to telumett- (PE21/37 and note #133).
