At the end of a Catalan word, voiced b, d, g normally lose their voicing and sound like p, t, c before a pause. Consequently, tub ends like cup, fred like fet, and mag like sac. Spelling cannot be recovered from the isolated sound alone.
Catalan resolves the ambiguity with a mixture of default ending rules, word-family evidence, and a limited set of lexical exceptions. This page explains the spelling choice; final consonants and devoicing explains the pronunciation and connected-speech effects.
Why listening alone fails
The three competing pairs differ clearly at the beginning of a syllable: p/b, t/d, c/g. At the end of a word before a pause or a voiceless consonant, however, both members are normally voiceless in the Central baseline and across Catalan more generally. Before another consonant, regressive voicing assimilation may change the surface sound without revealing which letter the word contains.
| Written pair | Same final outcome before a pause | Example contrast |
|---|---|---|
| p / b | [p] | cup / tub |
| t / d | [t] | fet / fred |
| c / g | [k] | sac / mag |
Han connectat un tub al cup per buidar-lo.
They connected a tube to the vat to empty it.
El mag ha fet el truc i ha deixat el sac a terra.
The magician performed the trick and left the sack on the floor.
The paired forms tub/cup and mag/sac, together with fet, illustrate final neutralization in plausible contexts. An English speaker may be tempted to maintain a voiced final consonant because English tub and tup contrast; standard Catalan does not use that contrast at the word edge. A Spanish cognate is also unreliable because the Catalan family and ending conventions decide the letter.
A useful diagnostic order is: locate stress, inspect the sound immediately before the final stop, and only then consult a relative. A stressed vowel activates the native p/t/c default; a consonant or unstressed vowel makes family evidence more direct. Finally, check the short lexical exception sets. Reversing that order leads learners to write amig merely because they found amiga.
After a stressed vowel or diphthong: p, t, c are the default
After a stressed vowel or stressed diphthong, native words normally end in p, t, c, even when a related form has medial b, d, or g:
- llop → lloba, rep → rebre, sap → saber;
- salut → saludable, buit → buidor, menut → menudesa;
- amic → amiga, abric → abrigar, plec → plegar.
El meu amic ha deixat l'abric a casa d'una amiga.
My friend left his coat at a female friend's house.
Amic and abric end in c by the stressed-vowel default. The family still matters because amiga and abrigar reveal the stem alternation; it does not authorize final g in these ordinary native words.
Aquest llop sembla ferotge, però la lloba és tranquil·la.
This wolf looks fierce, but the she-wolf is calm.
La salut dels infants és una responsabilitat compartida.
Children's health is a shared responsibility.
The final t of salut is not copied from saludable. The default explains why related forms can alternate in spelling as well as pronunciation.
The main stressed-vowel exceptions
A smaller group—especially learned words, loans, and certain lexical families—ends in b, d, g despite a preceding stressed vowel. These must be learned, preferably in families:
- b: adob, club, cub, tub, Carib;
- d: fred, fluid, sud;
- g: mag, buldog, estrateg, demagog, pedagog, including the productive learned ending -agog.
L'estrateg ha proposat un canvi durant la reunió del club.
The strategist proposed a change during the club meeting.
Avui fa fred al sud, i el fluid del motor s'ha congelat.
Today it's cold in the south, and the engine fluid has frozen.
There is no productive pronunciation trick that distinguishes final fred from a hypothetical spelling with t. Although the related feminine freda reveals d, the stressed-vowel default would predict t, so the exception still has to be learned. Honest mastery requires memorizing the common exceptions.
After a consonant or an unstressed vowel: let the family decide
After a consonant or an unstressed vowel, use the letter that appears before a vowel in a transparent inflected or derived relative:
| Final form | Related form | Final letter |
|---|---|---|
| camp | camperol | p |
| corb | corba | b |
| sort | sortejar | t |
| profund | profunditat | d |
| banc | banca | c |
| fang | fangós | g |
This ordinary family rule also explains learned words in -leg: biòleg → biòloga, filòleg → filòloga. They end after an unstressed vowel and are not exceptions to the stressed-vowel default above.
El corb ha baixat al camp i s'ha embrutat de fang.
The raven came down to the field and got muddy.
El llac és profund, però des del banc sembla tranquil.
The lake is deep, but from the bench it looks calm.
Do not choose the most frequent letter mechanically. Camp and corb sound alike at the final stop, but camperol versus corba resolves the spelling. Similarly, banc/banca contrasts with fang/fangós.
Lexical c even when the family shows g
Several frequent words ending after an unstressed vowel use c, although derivatives show g. High-value examples are:
- ànec → aneguet;
- càrrec → carregar;
- espàrrec → esparreguera;
- fàstic → fastigós;
- mànec → manegar;
- préssec → presseguer.
L'ànec s'ha menjat un tros de préssec prop de l'esparreguera.
The duck ate a piece of peach near the asparagus bed.
Aquest càrrec comporta una feina de vegades fastigosa.
This position involves work that is sometimes unpleasant.
These are genuine lexical exceptions to the simplest family test. The related forms are still useful because they organize the words into memorable pairs, but they do not determine the final graph automatically.
Productive endings and grammatical clues
Some morphological endings supply their own spelling:
- Gerunds end in -nt: cantant, fent, dormint, even where the t may be silent in speech.
- Nouns in -itud and -etud end in d: actitud, gratitud, quietud, solitud.
- The adjective gran has no final d, despite grandesa and engrandir.
- First-person forms such as tinc, puc, and vinc keep c, while other forms show g: tingui, pugui, vingui.
Està dormint amb una actitud de quietud absoluta.
He is sleeping with an air of absolute calm.
Tinc una gran responsabilitat i vull engrandir el projecte.
I have a great responsibility and want to expand the project.
Morphology here is more decisive than a neighboring word. Do not write a final letter merely because it becomes audible through liaison.
Regional speech can preserve or simplify neighboring final consonants differently, especially in clusters such as -nt and -mp. Those differences do not create regional spellings of salut, profund, camp, or temps. Likewise, (formal) careful pronunciation may make a cluster clearer without undoing final devoicing. Orthography remains tied to the word and its paradigm, not to how strongly a particular speaker releases the last consonant.
Editing exercise
Correct this message: L' amic del biòlec diu que el llop te fret i s'ha amagat al col.legi.
❌ L' amic del biòlec diu que el llop te fret i s'ha amagat al col.legi.
Incorrect — the sentence has final-obstruent, accent, apostrophe, and middle-dot errors.
✅ L'amic del biòleg diu que el llop té fred i s'ha amagat al col·legi.
The biologist's friend says the wolf is cold and has hidden at the school.
Biòleg belongs to the learned -leg class; freda reveals the d of fred. The acute accent in té, the attached apostrophe, and the middle dot require separate proofreading passes.
Common Mistakes
Copying the consonant from a voiced derivative after a stressed vowel
❌ La meva amig porta un abrig blau.
Incorrect — ordinary stressed-vowel finals use c in «amic» and «abric».
✅ La meva amiga porta l'abric blau.
My friend is wearing the blue coat.
Applying the p/t/c default to learned exceptions
❌ El biòlec treballa amb un tup de vidre.
Incorrect — the established forms are «biòleg» and «tub».
✅ El biòleg treballa amb un tub de vidre.
The biologist works with a glass tube.
Trusting final sound instead of a family
❌ El camp està ple de fanc.
Incorrect — «fangós» reveals the final g of «fang».
✅ El camp està ple de fang.
The field is full of mud.
Regularizing a lexical c/g exception
❌ L'àneg menja un prèsseg madur.
Incorrect — standard spelling has «ànec» and «préssec» despite «aneguet» and «presseguer».
✅ L'ànec menja un préssec madur.
The duck is eating a ripe peach.
Omitting a grammatical final letter because it is silent
❌ Estan treballan amb molta lentitu.
Incorrect — gerunds end in -nt and «lentitud» ends in d.
✅ Estan treballant amb molta lentitud.
They are working very slowly.
Key Takeaways
- Final devoicing makes p/b, t/d, and c/g sound alike before a pause, so sound alone cannot choose the spelling.
- After a stressed vowel or diphthong, native words normally use p, t, c; learn the common learned and loan exceptions in b, d, g.
- After a consonant or unstressed vowel, a transparent relative usually reveals the final letter.
- Memorize the frequent final-c exceptions such as ànec/aneguet and préssec/presseguer.
- Productive endings such as gerund -nt and noun -itud/-etud override phonetic uncertainty.
