Pronunciation
Complete Esperanto pronunciation guide: the 28-letter alphabet, IPA for each letter, stress rules, X-system and H-system for diacritics.
The 28-Letter Alphabet
Esperanto has 28 letters, each corresponding to exactly one sound. There are no silent letters, no ambiguous vowels, and no spelling exceptions. If you can read the letters, you can pronounce every Esperanto word correctly.
The full alphabet in order:
A B C Ĉ D E F G Ĝ H Ĥ I J Ĵ K L M N O P R S Ŝ T U Ŭ V Z
(lowercase: a b c ĉ d e f g ĝ h ĥ i j ĵ k l m n o p r s ŝ t u ŭ v z)
Letter-by-Letter Pronunciation with IPA
Vowels (5)
| Letter | IPA | Description | Example |
|---|---|---|---|
| A | /a/ | Like "a" in "father" — open, unrounded | patro /ˈpatro/ |
| E | /e/ | Like "e" in "bed" — mid-front, slightly tense | bela /ˈbela/ |
| I | /i/ | Like "ee" in "see" | libro /ˈlibro/ |
| O | /o/ | Like "o" in "more" — round, never diphthong | domo /ˈdomo/ |
| U | /u/ | Like "oo" in "moon" | urbo /ˈurbo/ |
Key point: Esperanto vowels are pure — never diphthongized. "E" is always /e/, never the English diphthong /eɪ/ as in "say". "O" is always /o/, never /oʊ/ as in "go".
Consonants — Standard (17)
| Letter | IPA | Description | Example |
|---|---|---|---|
| B | /b/ | Like "b" in "book" | bona /ˈbona/ |
| C | /ts/ | Like "ts" in "cats" — always this sound | cento /ˈtsento/ |
| D | /d/ | Like "d" in "dog" | domo /ˈdomo/ |
| F | /f/ | Like "f" in "farm" | fari /ˈfari/ |
| G | /ɡ/ | Like "g" in "get" — always hard, never /dʒ/ | granda /ˈɡranda/ |
| H | /h/ | Like "h" in "hat" | havi /ˈhavi/ |
| K | /k/ | Like "k" in "king" | kato /ˈkato/ |
| L | /l/ | Like "l" in "lamp" — clear, not dark | libro /ˈlibro/ |
| M | /m/ | Like "m" in "man" | manĝi /ˈmandʒi/ |
| N | /n/ | Like "n" in "name" | nomo /ˈnomo/ |
| P | /p/ | Like "p" in "pen" — less aspirated than English | paroli /paˈroli/ |
| R | /r/ | Rolled/trilled "r" — like Spanish "r" | rapida /raˈpida/ |
| S | /s/ | Like "s" in "sun" — always /s/, never /z/ | salto /ˈsalto/ |
| T | /t/ | Like "t" in "stop" — less aspirated than English | tago /ˈtaɡo/ |
| V | /v/ | Like "v" in "voice" | vidi /ˈvidi/ |
| Z | /z/ | Like "z" in "zone" | zorgi /ˈzorɡi/ |
Special Letters with Circumflex (6)
These 6 letters use circumflex (hat) diacritics and are among Esperanto's most distinctive features:
| Letter | IPA | Description | Example |
|---|---|---|---|
| Ĉ | /tʃ/ | Like "ch" in "church" | ĉambro /ˈtʃambro/ |
| Ĝ | /dʒ/ | Like "j" in "judge" | ĝardeno /dʒarˈdeno/ |
| Ĥ | /x/ | Like "ch" in German "Bach" or Scottish "loch" | ĥemio /ˈxemio/ |
| Ĵ | /ʒ/ | Like "s" in "measure" or "j" in French "jour" | ĵurnalo /ʒurˈnalo/ |
| Ŝ | /ʃ/ | Like "sh" in "ship" | ŝipo /ˈʃipo/ |
| Ŭ | /w/ | Like "w" in "water" — only used in diphthongs aŭ, eŭ | aŭto /ˈawto/ |
Note on Ĥ: The /x/ sound is rare in English but common in many European languages. It occurs in relatively few Esperanto roots. Some speakers substitute /k/ in colloquial speech, but /x/ is standard.
Note on Ŭ: The letter ŭ (u-breve) is a semi-vowel that only appears in the diphthongs aŭ (/aw/ as in "cow") and eŭ (/ew/ as in "few"). It never stands alone.
The Semi-vowel J
| Letter | IPA | Description | Example |
|---|---|---|---|
| J | /j/ | Like "y" in "yes" — always a consonant in Esperanto | jes /jes/ |
Note: J is a consonant, not a vowel. It appears in words like jes (yes), jam (already), and in the plural ending -j (libroj = books, pronounced /-oj/ as in "boy").
Stress Rules
Stress in Esperanto is completely regular — always on the penultimate syllable (second to last):
| Word | Syllables | Stress | Pronunciation |
|---|---|---|---|
| libro | lib-ro | lib-ro | /ˈlibro/ |
| amiko | a-mi-ko | a-mi-ko | /aˈmiko/ |
| familio | fa-mi-li-o | fa-mi-li-o | /famiˈlio/ |
| universitato | u-ni-ver-si-ta-to | u-ni-ver-si-ta-to | /universitato/ |
Exception: Words of only one syllable are stressed on that syllable (mi, vi, la, al, de, da...).
Important implication: As words take suffixes, stress shifts accordingly:
- libro → libreto (little book): li-bre-to
- patro → patreto (dear little father): pa-tre-to
Diphthongs
Esperanto has two standard diphthongs:
| Diphthong | Sound | Example |
|---|---|---|
| aŭ | /aw/ like "ow" in "cow" | aŭto (car), aŭskulti (to listen) |
| eŭ | /ew/ like "ew" in "few" | Eŭropo (Europe), neŭtrala (neutral) |
Typing the Diacritics: X-System and H-System
The 6 circumflex letters (ĉ, ĝ, ĥ, ĵ, ŝ, ŭ) are not on standard keyboards. Two widely used workarounds exist:
X-System (Recommended)
Add x after the base letter:
| Typed | Result |
|---|---|
| cx | ĉ |
| gx | ĝ |
| hx | ĥ |
| jx | ĵ |
| sx | ŝ |
| ux | ŭ |
Why X-system? The letter X does not natively exist in Esperanto, so there's no ambiguity. Type "cxi tio estas bona" and a converter immediately knows it means "ĉi tio estas bona." Most modern Esperanto software (including Lernu.net, many editors, and online tools) accepts X-system input.
H-System (Older, Less Preferred)
Add h after the base letter:
| Typed | Result |
|---|---|
| ch | ĉ |
| gh | ĝ |
| hh | ĥ |
| jh | ĵ |
| sh | ŝ |
| u (no change in most H-system variants) | ŭ |
Problem with H-system: H already exists in Esperanto as its own letter, causing ambiguity. "Shako" (chess) becomes "sako" (bag) if the H is lost. X-system is unambiguous.
Keyboard Solutions (Recommended for Regular Typing)
- Windows: Use the Tajpi input method or configure a custom keyboard layout
- Mac: Use the built-in Unicode input or install an Esperanto keyboard layout
- Mobile: Android and iOS have Esperanto keyboard options in the keyboard settings
- Web/email: X-system is perfectly acceptable and universally understood
Common Pronunciation Mistakes for English Speakers
| Mistake | Wrong | Correct | Explanation |
|---|---|---|---|
| Diphthongizing vowels | /eɪ/ for E | /e/ | Esperanto E is a pure vowel, not "ay" |
| Diphthongizing O | /oʊ/ for O | /o/ | Esperanto O is a pure vowel, not "oh" |
| Pronouncing C as /s/ or /k/ | /sento/ or /kento/ | /tsento/ | C is always /ts/ like "cats" |
| Pronouncing G as /dʒ/ | /dʒardeno/ | /ɡardeno/ | G is always hard /ɡ/ — use Ĝ for /dʒ/ |
| Pronouncing J as /dʒ/ | /dʒes/ | /jes/ | J is /j/ like "yes" |
| Pronouncing S as /z/ between vowels | /rozo/ → /rɔzo/ | /roso/ | S is always /s/ |
| Weak/unclear rolled R | flap or approximant | trilled /r/ | Practice the trill; many find it easier in Esperanto than Spanish |
| Wrong stress | a-MI-ko incorrect | a-MÍ-ko | Second syllable, not first |
| Skipping the Ĥ | /emio/ | /xemio/ | Ĥ is a real sound; try clearing your throat softly |
| Treating Ŭ as a vowel | /aʊ/ diphthong confusion | /aw/ | The breve indicates it's a glide, like English W |
