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.

adverb. at hand
A word glossed “at hand” in the phrases Es sorni heruion an “the Eagles of the Lords are at hand” and Sorni Númevalion anner “the Eagles of the Powers of the West are at hand” (SD/290). Luinyelle suggested anner might be a plural past tense of anya- “arrive”, so that 2nd phrase might actually mean “✱the Eagles of the Powers of the West arrived”. This is consistent with the Adûnaic form of the phrase: Ad. narîka ’nBâri ’nAdûn yanâkhim (SD/251), where the last word in the phrase appears to be a form of the verb: nakh- “come”, so that yanâkhim = “✱are coming”.
an-
prefix. intensive prefix
ana-
prefix. to, towards
horya-

i
article. the
ilq(an)ar

Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. ilquaurë “all the day”, since the later word for “day” is aurë.
lai
adverb. very
laime
noun. shadow (cast by an object or form), shade
A noun in The Etymologies of the 1930s variously glossed “shade”, “shadow (cast by an object or form)”, and “shadow cast by a thing” under different iterations of the root ᴹ√DAY “shadow” (Ety/DAY; EtyAC/DAY). This root was primarily used for N. dae “shadow” in N. Dor-Daedeloth “Land of the Shadow of Dread”; in later writings the Dae- element in that name seems to have become dae(r) “great” (WJ/183), so I suspect ᴹ√DAY “shadow” and its derivatives were abandoned.

lálar

Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. ilítë “of all kinds, of all sorts” using il- “every” and the later suffix -itë, as in taitë “of that sort”.
san(an)de
adverb. to the very degree
A correlative appearing in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/111), a combination of ᴹQ. sa “that [anaphoric]” and ᴹQ. -n(de) “degree”.
