cimni gismu

x1 is infinite/unending/eternal in property/dimension x2, to degree x3 (quantity)/of type x3.

Also everlasting, eternity, (= cimnytei), eternal (= cimnyteikai or temcimni). See also vitno, renvi, munje, fanmo, sisti.

In notes:

brabra
b1 is huge/enormous/very big in property b2 with criterion b3.
caibra
b1=c1 is huge/enormous/colossal in property b2=c2 to observer b3=c3.
camganra
g1=c1 is vast/very wide in (2nd most significant) dimension g2=c2 with observer g3=c3.
cimny'efku
x1 is infinitely recursively related to x2 by applying infinite levels of recursion to predicate relation x3 (ka with two ce'u)
kancuka'e
x1 (set, group, structure, category, class, etc.) has cardinality less than or equal to aleph-null; x1 is mathematically countable (including the option of being finite).
selte'abra
b1=t2 is huge/enormous/tremendous in property b2 and feared by b3=t1.
tcebra
b1=m1 is huge/enormous/very big in property b2 with criterion b3.
to'e zei kancuka'e
x1 (set, group, structure, category, class, etc.) has cardinality strictly more than aleph-null; x1 is mathematically uncountable.
tolcimni
c1 is finite/ending/unlasting/limited in property/dimension c2, to degree c3 (quantity)/of type c3
vitno
x1 is permanent/lasting/[eternal] in property x2 (ka) by standard x3 [time-span/expectant one].
