A limited number of Esperanto adverbs do not end with the regular adverbial ending (-e). Some of these function as more than just adverbs, such as hodiaŭ "today" [noun or adverb] and ankoraŭ "yet, still" [conjunction or adverb]. Others are part of the correlative system, and have not been repeated here.

ankoraŭ (still, yet)

apenaŭ (barely)

baldaŭ (soon)

do (therefore)

for (away)

hodiaŭ (today)

hieraŭ (yesterday)

jam (already, yet)

ĵus (just now)

morgaŭ (tomorrow)

nun (now)

plej (most)

pli (more)

plu (beyond, further)

tamen (however, nevertheless)

tre (very)
