pol (2) adj. "large, big (strong)". Since this would be the sole example of a monosyllabic Quenya adjective, it may be that Tolkien is here citing the root POL rather than a complete word. Cf. polda.
Quenya
polda
big
polda
adjective. big, big; [ᴹQ.] strong, burly; [ᴱQ.] mighty, powerful
pol
large, big (strong)
Poldor
breaker up of the hard / tough
Poldor, Poldomo noun "breaker up of the hard / tough", Poldor- "land-breaker?", variant forms of Poldórëa, q.v., introduced at a time when Tolkien did not want the root POL to refer to strength or mightiness (PE17:181), cf. polda from an earlier source.
poldavë
adverb. strongly
A neologism coined by Paul Strack in 2018 specifically for Eldamo, an adverb form of the adjective Q. polda “strong”. Tamas Ferencz instead suggested ᴺQ. pollie could be an adverb meaning “hard, strongly” based on empollie which seems to mean “✱harder” in á rike empollie as an alternative to the phrase á rike amríkie “try harder; (lit.) try with more trying” (PE17/94, 167), but this use of pollie seems pretty tenuous to me, so I’d stick with the more straightforward poldave.
poldorë
strong, burly
poldorë noun? (not glossed, derived from polda "strong, burly": possibly "strength" as an abstract) (POL/POLOD)
-úmë
large
-úmë (3) suffix "large" (of quantity)", as in liyúmë "host" (VT48:32)
Turcafinwë
strong, powerful (in body) finwë
Turcafinwë masc. name, "strong, powerful (in body) Finwë", masc. name; he was called Celegorm in Sindarin. Short Quenya name Turco. (PM:352), compare #turco "chief" (q.v.)
alat-

melehta
mighty
melehta adj. "mighty" (PE17:115), cf. meletya
melehta
adjective. mighty
An adjective for “mighty” derived from the root √MBELEK in a page of notes having to do with “large & small” words, probably from the late 1960s (PE17/115), apparently from the primitive form ✱✶mbelektā (with [kt] > [ht]). A variant form meletya appears with the 2nd-plural possessive suffix -lda as Meletyalda “your mighty” in the Quendi and Eldar essay of 1959-60 (WJ/369), likely from the primitive form ✱✶mbelekya (with [kj] > [tj]). This variant form has a more typical primitive adjective suffix ✶-ya, but is inconsistent with the attested Sindarin cognate S. belaith, so I’d stick with melehta for purposes of Neo-Quenya.
meletya
mighty
#meletya adj. "mighty", isolated from meletyalda adjective with suffix "your mighty" = "your majesty" (see -lda; meletya = *"mighty"). In full Aran Meletyalda "king your mighty" = "your majesty" (WJ:369). Compare melehta.
meletya

túra
big, great
túra adj. "big, great" (PE17:115), related to words for power and apparently referring to a more abstract greatness than words like haura "huge". Cf. taura, túrëa. Apparently initial element of Túrosto.
úra
large
úra (2) adj. "large" (UR), probably obsoleted by #1 above
polda adj. "big" (PE17:115), "strong, burly" (POL/POLOD)
