Esperanto Interjections: Ho, Nu, Ve and Sound Words

By Michael McGettrickUpdated 12 October 2026

An interjection takes no ending and sits outside the sentence: , ! is oh, how lovely! Give one an ending, though, and it becomes an ordinary word: the noise boj gives , to bark.

WordFeelingExample
surprise, sorrow, or calling out, !
sudden and sharp; doubled, a laugh !
wistful: longing, regret, !
ajpain: ouchAj! !
woe, aimed with !
alas, oh dear, .
well, so, come on, .
disgust, shame !
huraa cheerHura! !
, hejhey: getting attention, !

Now use it: three quick questions on the chart above. The full practice is further down.

Each sentence has one wrong word. Tap it.

The glosses: how lovely!; ha ha!; if only I knew!; ouch, my foot!; woe is me!; oh dear, it is too late; well, let us begin; shame on you!; hooray, we won!; hey, you there!

JoyWoe
  1. hura
  2. ho
  3. aĥ
  4. ho ve
  5. ve al mi

is by far the commonest. In the frequency list this course uses it sits at rank 85, among the pronouns; is at 382, at 589, at 862.

Outside the sentence

An interjection has no job in the grammar. Delete it and the sentence is still whole:

  • , . - Oh, I did not know that.
  • . - I did not know that.

So it never takes -j, -n or any other ending: is whatever surrounds it. A comma or an exclamation mark sets it off, and an exclamation mark raises the :

  • Aj! . - Ouch! That hurts.

Unlike Spanish, Esperanto has no opening mark: !, never ¡!. And one per turn is plenty. is a fixed pair; , , , is a breakdown.

Ho ve: alas

brings the surprise, the misery, and together they are the standard alas, or a milder oh dear:

  • , ! - Oh dear, I forgot the key!
  • , . - Alas, the time has gone.

Alone, is heavier and older-sounding. It is not a verb, so it cannot take an object; it aims at a person with :

  • ! - Woe is me!
  • ! - Woe to the defeated!

is what an English speaker writes by analogy with woe is me, and it is wrong for that reason: there is no verb for to be the object of.

Nu: well, and now

is the nudge: well, so, right, come on. It opens a turn, moves a story on, and buys a second while you think:

  • , . - Well, let us begin.
  • , . - Well, I t know.
  • , ! - Go on, then!

In a chain of reasoning it can also mean now, bringing in the next step, much as English now does:

  • . , Sokrato . - All men die. Now, Socrates is a man.

Outside an argument like that one, read it as well. Its partner in conversation is , so, then, which closes a thought where opens one; both are in spoken Esperanto.

Fi, and the fi- prefix

fi- (morally bad)-aĉ- (shoddy, poor quality)the endingWhat do the colours mean?

is one syllable of disgust: ! is shame on you! With an ending it becomes a word, and as a prefix it condemns:

WordEnglish
base, contemptible
a scoundrel
a vile act

The suffix -- also disapproves, but of quality, not morals. Put both on one root and you get two different complaints:

Rootfi-: behaves badly-aĉ-: shoddy
, a vicious dog, a mangy dog
fidomo, a house of ill repute, a hovel

The two overlap at the edges, and speakers do not always keep them apart. The tendency is what matters: - judges, -- sneers. The interjection and the prefix - have separate pages here.

Every noise takes an ending

the endingWhat do the colours mean?

The four endings work on any root, and a root that started life as a noise is no exception. So interjections grow families:

NoiseWith an endingEnglish
veo, veia lament; to lament
homesickness (home-woe)
base, contemptible

is the best argument for learning the interjections: no word list prepares you for it, and once you know you cannot misread it.

  • . - He felt homesick.

Sound words become verbs

the endingWhat do the colours mean?

Esperanto writes noises much as English does: bum for a thud, plaŭd for a splash, boj for a dog. Add -i and the noise is a verb; add -o and it is the sound itself:

NoiseVerbNounEnglish
bojto bark; a bark
miaŭmiaŭimiaŭoto miaow; a miaow
plaŭdplaŭdiplaŭdoto splash; a splash
tiktaktiktaki-to tick
zum-to buzz

Then it conjugates like any verb:

  • . - The dog barked all night.
  • miaŭas ? - Who is miaowing behind the door?
  • to barkto bark
  • to ring (a bell)to ring (a bell)
  • to whistleto whistle

Many sound verbs are ordinary roots with no written noise behind them: (ring, of a bell), (whistle), (groan). When you do not know an s own verb, is the general one: the cry of any animal.

  • . - The donkey brayed.

The spelling of animal noises varies more than the rest of the language; a cockerel, for one, is written several ways. The interjections in the first table are the settled core.

Mistakes English speakers make

WrongRightWhy
! ! is not a verb: it takes
! !Aj! ! means or; ouch is aj
miaŭ. miaŭas.a noise needs -as to be a verb
¡!!no opening exclamation mark

What to do next

  1. Learn , aj, , and first; they cover most feelings.
  2. Make verbs from three noises you hear today, with -i.
  3. Then read spoken Esperanto for and in conversation.

Frequently asked questions

How do you say alas in Esperanto?
. Ho carries the surprise and the woe, and together they are the standard alas, or a milder oh dear: , . on its own is heavier and older-sounding, and it aims at a person with : , woe is me.
What is the difference between ho, ha and in Esperanto?
Ho is the broad one: surprise, sorrow, or calling to someone (ho, !). Ha is short and sharp, a sudden realisation, and doubled it is laughter: ha ha! is the wistful one, for longing and regret: , ! Ho is by far the commonest of the three.
Is an interjection in Esperanto?
Yes: it is the word for well, so, come on. , is well, let us begin. Speakers use it to open a turn and to buy a second while they think, much as English uses well. In a chain of reasoning it can also mean now, introducing the next step: , Sokrato .
What is the difference between fi- and -aĉ- in Esperanto?
Fi- condemns behaviour; -aĉ- complains about quality. A o is a scoundrel, a o is a hovel, and a fidomo is a house of ill repute, however sound its walls. Both come from disapproval, and they overlap at the edges, but the tendency is clear: fi- is moral, -aĉ- is shoddy.
How do you make a verb from a sound in Esperanto?
Add -i to the noise. Boj is a dog's bark, so is to bark and is a bark; miaŭ gives miaŭi, to miaow; zum gives , to buzz. Then it conjugates like any verb: , the dog barked. English has to coin each verb separately; Esperanto builds it from the noise.
