Catalan g changes sound according to the following vowel, while gu preserves hard /g/ before e/i. The parallel spelling qu preserves /k/ before e/i. In those environments the written u is normally silent; a diaeresis in gü/qü makes it audible. These are not isolated exceptions but one coordinated spelling system.
This page uses contemporary Central Catalan. Unlabelled examples are neutral standard forms. Central j and soft g are taught as fricative /ʒ/; Valencian commonly uses a voiced affricate /dʒ/ in comparable words (regional: Valencian).
Hard and soft g
The following vowel selects the basic value of g:
| Spelling | Central value | Examples |
|---|---|---|
| ga, go, gu | hard /g/ | gat, got, gust |
| ge, gi | soft /ʒ/ | gel, gent, girar |
| gue, gui | hard /g/; u silent | guerra, guitarra |
| güe, güi | /gw/; u pronounced | següent, pingüí |
El gat gira el cap quan veu la gent.
The cat turns its head when it sees the people.
The g of gat is hard /g/ before a. The g of gira and gent is soft /ʒ/ before i/e in the Central model. English g has a partially similar hard/soft alternation, but English soft g is normally affricate /dʒ/, not Central Catalan fricative /ʒ/.
Guarda el got gros al costat de la garrafa.
Put the large glass beside the carafe.
All four g spellings are hard because they precede a/o. Between vowels or after certain sounds, /g/ is often realized as the softer approximant [ɣ] in fluent Central speech. That is a contextual pronunciation, not a new spelling or a change to soft g /ʒ/.
J keeps the soft sound before a, o, and u
Native spelling normally uses j where /ʒ/ precedes a/o/u: ja, jardí, jove, dijous, just. Before e/i, ordinary inherited patterns favor soft g, though j occurs in some loans, learned words, and names, such as jersei and Jesús.
La Júlia juga al jardí cada dijous.
Júlia plays in the garden every Thursday.
Each j has Central /ʒ/. Spanish speakers must resist the Spanish j or soft g sound /x/; Catalan jardí does not begin like Spanish jardín. English speakers should avoid adding the stop closure of English j /dʒ/.
En Jordi porta un jersei groc.
Jordi is wearing a yellow sweater.
Jordi has ordinary j before o, while jersei preserves j before e as an established lexical spelling. The latter does not overturn the productive g/j distribution.
The contrast between guerra “war” and gerra “jug” is almost entirely carried by the consonant:
La gerra es va trencar durant la guerra.
The jug broke during the war.
In Central Catalan, gerra begins /ʒ/ because g directly precedes e. Guerra begins /g/ because gu protects the hard value and the u is silent.
Silent u in gue and gui
Before e/i, plain g would be soft. The digraph gu blocks that reading and represents hard /g/. Its u is not a vowel or glide.
En Guillem toca la guitarra a l'esquerra.
Guillem plays the guitar on the left.
In Guillem and guitarra, gui begins with /g/ followed directly by /i/. Do not insert [w] or an extra u vowel. Esquerra illustrates the parallel qu mechanism for /k/.
Aquesta guerra sembla molt llarga.
This war seems very long.
Guerra begins /gɛ-/, not /gwɛ-/ and not Central /ʒɛ-/. Its stressed open e and the trill rr are separate pronunciation decisions layered on top of the digraph.
When gu precedes a/o, it is not this silent-u digraph: the u is pronounced as a vowel or glide, as in guant and aigua.
He deixat els guants prop de l'aigua.
I've left the gloves near the water.
The u is audible in both guants and aigua because gu is followed by a, not e/i.
When i rather than u bears a diaeresis, it normally marks hiatus instead; see diphthongs and hiatus. The two uses belong to the same writing system but solve different pronunciation problems.
QU: /k/ with two possible kinds of u
The letter q normally appears as qu. Before e/i, qu represents /k/ and its u is silent: que, qui, paquet, màquina. Before a/o, the u is pronounced, usually as the glide quota, qualsevol*.
| Pattern | Role of u | Examples |
|---|---|---|
| que, qui | silent | que, quinze, paquet |
| qua, quo | pronounced | quatre, quan, quota |
| qüe, qüi | pronounced because of ¨ | qüestió, aqüífer |
Qui ha deixat aquest paquet aquí?
Who left this parcel here?
Every qu before i/e has silent u and yields /k/. Aquí is written with q and an accent on final í; the accent controls stress, not whether u is heard.
Quan arribin, comprarem quatre quaderns.
When they arrive, we'll buy four notebooks.
In quan and quatre, u is pronounced as part of /kw/. In quaderns the same is true because qu precedes a. No diaeresis is needed in qua.
The diaeresis: gü and qü
Two dots over u explicitly cancel the normal silent-u reading before e/i. Compare plain guitarra with pingüí, and plain que with qüestió.
El pingüí és el símbol d'una entitat lingüística.
The penguin is the symbol of a linguistic organization.
Pingüí and lingüística pronounce u as a glide [w]. The acute accent in pingüí separately marks final stress. Both diacritics are essential and perform different jobs.
La qüestió següent és més complexa.
The following issue is more complex.
Both qüe in qüestió and güe in següent include audible [w]. Without the diaeresis, the usual que/gue reading would silence u.
Spanish knowledge helps with gü, but it can mislead with qü: contemporary Spanish writes cuestión, whereas Catalan writes qüestió. English has no comparable systematic silent-u/diaeresis contrast.
Stress, syllables, and connected speech
The silent u in gue/gui/que/qui cannot form a syllable. Thus guitarra is gui-tar-ra, and paquet is pa-quet. Audible u in güe/güi/qüe/qüi normally forms a glide with the following vowel, as in se-güent and qües-ti-ó.
Stress and vowel reduction apply after this mapping. In Central Catalan, the first e of guerra is stressed and remains open /ɛ/, while unstressed vowels in guitarra reduce normally. Do not let the unfamiliar spelling move stress onto u.
For slow practice, make the contrasting spellings deliberate:
Guitarra, pingüí, paquet, qüestió.
Slow practice form: Guitar, penguin, parcel, issue.
In natural connected speech, the same sound mappings remain while /g/ may lenite and unstressed vowels reduce:
El lingüista guarda la guitarra dins d'aquest paquet.
Natural connected form: The linguist keeps the guitar inside this parcel.
—La u de qüestió sona? —Sí, per això porta dièresi.
—Is the u in qüestió pronounced? —Yes, that's why it has a diaeresis.
This dialogue is neutral conversational Catalan (informal). The ï in dièresi belongs to the wider diaeresis system and marks hiatus; on this page, the crucial sign is ü, which makes u audible.
Regional scope
The hard /g/ and /k/ spelling mechanisms gu/qu are shared broadly. The largest regional difference here concerns soft g/j: Central commonly has fricative /ʒ/, while Valencian commonly uses affricate /dʒ/ (regional: Valencian). Northwestern, Balearic, Northern, and Alguerese realizations vary in affrication, voicing, and the detailed treatment of individual loanwords (regional). Lenition of hard /g/ also varies by position, formality, and dialect.
IEC and AVL spelling both preserve the functional contrast between silent u and diaeretic ü. A regional accent may change the exact consonant, but it does not license dropping the diaeresis from qüestió, següent, or pingüí.
Common Mistakes
1. Reading soft g/j with Spanish /x/.
❌ La Júlia gira, amb el so castellà de jota.
Incorrect in Central Catalan — j and soft g use /ʒ/, not Spanish /x/.
✅ La Júlia gira a l'esquerra.
Júlia turns left — use Central /ʒ/ in Júlia and gira.
2. Pronouncing u in gue/gui.
❌ En Guillem toca la gu-itarra.
Incorrect — u is silent in gui before i.
✅ La Gisela toca la guitarra cada vespre.
Gisela plays the guitar every evening — gui begins /gi/.
3. Silencing u despite a diaeresis.
❌ Pingüí, pronunciat com si s'escrivís pinguí.
Incorrect — ü requires an audible u glide.
✅ El pingüí neda de pressa.
The penguin swims quickly — pronounce [w] in güí.
4. Adding a diaeresis before a or o.
❌ Qüatre qüaderns.
Incorrect — u is already pronounced in qua, so no diaeresis is used.
✅ He comprat quatre quaderns.
I've bought four notebooks.
5. Treating every qu as silent-u /k/.
❌ Quan, pronunciat com can.
Incorrect — u is audible in qua.
✅ Quan comprarem quatre quaderns?
When will we buy four notebooks? — pronounce /kw/ in all three qua sequences.
Key Takeaways
Read g as /g/ before a/o/u and Central /ʒ/ before e/i. Use gu to preserve /g/ and qu for /k/ before e/i, normally with silent u. Add a diaeresis—gü/qü—when that u must be heard. Before a/o, u in gu/qu is already pronounced and needs no diaeresis.
