There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

hat-

verb. to break asunder

A verb in The Etymologies of the 1930s based on the root ᴹ√SKAT “break asunder” and thus presumably with the same meaning (Ety/SKAT).

Neo-Quenya: For purposes of Neo-Quenya, I generally use [ᴺQ.] hat- to mean “throw” derived from ᴹ√KHAT, so I assume this basic verb hat- “break asunder” was archaic and replaced in ordinary speech by more distinctive verb forms ᴹQ. terhat- and ᴹQ. askat- of similar meaning.

hat-

verb. through[?] down[?]

The Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s had a verb ᴱQ. hata- based on the early root ᴱ√HATA “hurl, fling” (QL/39; PME/39). The verb was variously glossed “hurl” [hata-] and “I fling” [hatin]. In this period, it had a Gnomish cognate G. hada- “throw at, aim at” (GL/48). The root reappeared in The Etymologies of the 1930s as ᴹ√KHAT “hurl”, but in that document the root had only Noldorin derivatives like N. hedi [had-] “hurl” and N. hador or hadron “thrower” (Ety/KHAT).

ᴹ√KHAT also appeared on a rejected page of roots in the Quenya Verbal System (QVS) of 1948 where it was glossed “hurl, cast, send through air, loose from hand but not nec[essarily] fast”, contrasted with another root ᴹ√RIP “fling, hurl, of something long like arrow, spear, shaft” (PE22/127 note #152). Thus in this document it seems ᴹ√RIP was “hurl fast” and ᴹ√KHAT “throw but not always fast”. This rejected page had what appears to be Quenya verb forms corresponding to both roots: past form ᴹQ. rimpe “hurled” and [?stem form] ᴹQ. hat. The latter was followed by a hard-to-read gloss “through[?] down[?]”.

Later still, Tolkien had the noun Q. hatal “spear” in notes from the late 1960s (VT49/14), indicating the ongoing validity of the root √KHAT.

Neo-Quenya: Based on Q. hatal “spear”, I think ᴹ√RIP “hurl [fast] of an arrow/spear/shaft” was a transient idea. As such, I would use ᴺQ. hat- for “hurl, fling, ✱throw”. Note that this conflicts with ᴹQ. hat- “break asunder” from The Etymologies (Ety/SKAT), but I assume this verb form is archaic and replaced by ᴹQ. terhat- or ᴹQ. askat- in modern Quenya; see the entry for ᴹQ. hat- for further discussion.

hat

noun. ridge, comb, crest

A word appearing in the Declension of Nouns from the early 1930s glossed “comb, ridge” (PE21/19) and “ridge (comb, crest)” (PE21/27). It perhaps refers to raised formations of various kinds, geological as well as things like the comb or crest of a bird or the ridge of a roof.

top-

verb. to cover

tópa

noun. roof

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).

tópa-

verb. to roof

A verb for “to roof” in The Etymologies of the 1930s under the root ᴹ√TOP “cover, roof” (Ety/TOP).
