The Quenya allative suffix indicating motion towards; see that entry for discussion.
Conceptual Development: In Tolkien’s earlier writings, it had other forms like ᴱQ. -nta or -tta (PE14/46, 78).

root. two, double, bi-, di-; back, re-; across, over, lying from side to side, two, double, bi-, di-; back, re-, [ᴹ√] again, twice; [ᴱ√] dual; [√] across, over, lying from side to side
As the main root for “two”, √AT dates all the way back to the Qenya Lexicon of the 1910s where ᴱ√ATA appeared with the gloss “dual” (QL/33). At this very early stage, its derivatives had mainly to do with pairs such as ᴱQ. aqi “a brace, a couple of, both” and at- “bi-, twi-”, whereas the earliest Quenya word for “two” was ᴱQ. yúyo (PE14/49). Later on, Q. yúyo became “both” whereas “two” became Q. atta.
In The Etymologies of the 1930s this root appeared as ᴹ√AT(AT) (Ety/AT(AT)) with variants ᴹ√ATTA which became the basis for Quenya atta “two” (Ety/ATTA) and ᴹ√TATA which became the basis for Noldorin tâd “two” (Ety/TATA); these numerals retained this form thereafter into the Quenya and Sindarin of the 1950s and 60s (VT42/24-26). In the 1930s, the ᴹ√TATA variant took on the sense “double” in Quenya, and the ᴹ√ATTA variant took on the sense “across” in Noldorin. The base root ᴹ√AT had the sense “again, back”, as seen in both Quenya and Noldorin prefixes ᴹQ. at(a)-, N. ad- “back, again, re-” (Ety/AT(AT)).
This root continued to appear in the 1950s and 1960s, retaining its various meanings of “two” (VT42/27), “back, again” (PE17/148) and “across” (VT43/33). Tolkien explored the origin and development of this root at some length in his essays on Elvish numerals from the late 1960s, connecting it to √AT(AR) “father” via various Elvish finger names (VT48/19).
enki
pronoun. that by you over there (addressing or writing to someone at a distance)
ad-
prefix. back, again, re-
ad-
prefix. back, again, re-
gladh-
verb. to laugh, to laugh [at a joke], *guffaw
This word is not compatible with the name Lalaith “Laughter” attested in The Silmarillion. The most likely explanation of this name is that it is the unattested verb ✱lala- “laugh” with the abstract noun suffix -th seen in tirith “watch(ing)” and sirith “flowing”. This indicates a primitive form ✶lala- instead of ✶glada- (both primitives produce Quenya lala-). If you were to accept gladh- as the Sindarin word for “laugh”, then the word for “laughter” would perhaps be the equivalent abstract noun ✱gladhath, and the name Lalaith might be a mix of Quenya and Sindarin. @@@ Neo-Sindarin uses
Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
at(a)-
prefix. back, again, re-
waryallume
adverb. *at a different time
ata Reconstructed
root. ATA
rukta-
verb. to belch smoke, spout smoke; to cause to smoke; to smoke at a pipe
A word appearing as ᴱQ. rukta- “belch smoke, spout smoke - cause to smoke; smoke at pipe” in the Qenya Lexicon of the 1910s, derived from the early root ᴱ√RUKU “smoke, reek” (QL/80).
Neo-Quenya: I think this word can be revised to ᴺQ. uruhta- “to (cause to) smoke; to belch smoke” as a derivative of the later root √USUK, which I use as the basis for “smoke” words in Neo-Eldarin; this neologism was first coined by Shihali in a Discord chat on 2018-04-20.
A prefix for “double” based on √AT of similar meaning used in various words like atendëa “double-middle” (RC/728) and atamaitë “two-handed” (PE17/162). In notes from around 1959 Tolkien said it could also be used for “again”, but “only in literal sense of second time, double” (PE17/166). Compare ataquanta- “refill” = “fill a second time” vs. the more ordinary word for “refill” = enquanta-.
Conceptual Development: The Etymologies of the 1930s translated the prefix ᴹQ. at(a)- as “back, again, re-” under the root ᴹ√AT(AT), which in this document was glossed “again, back” (Ety/AT(AT)). This distinction can be seen in 1940s ᴹQ. at-tul- “return” vs. later entul- from the 1950s and 60s. Earlier still the Qenya Lexicon of the 1910s had ᴱQ. at-, att-, or atta- “bi-, twi-” under the early root ᴱ√ATA “dual” (QL/33).
Neo-Quenya: For purposes of Neo-Quenya, I would use at(a)- mainly in the sense “double, bi-, twi-”, and would only use it for the sense “re-” in the limited sense “do a second time” as described above. However, based on its meaning in The Etymologies, at(a)- is popular as a prefix for “re-” in many neologisms, but I would avoid this because these 1930s glosses predate Tolkien’s introduction of en- “re-”.
