Krom sets one participant, thing, or action apart from the rest of a statement. That separation supports two nearly opposite readings: exception (“all except Ana”) and addition (“besides Ana, also Petro”). Polarity, totalizing words such as ĉiuj, and additive signals such as ankaŭ tell the reader which interpretation is intended.
The shared core: consider this item separately
In both uses, the krom phrase is removed from the main group for separate consideration:
Ĉiuj kolegoj krom Ana jam respondis.
All the colleagues except Ana have already replied.
Krom Ana, ankaŭ Petro jam respondis.
Besides Ana, Petro has also replied.
The first sentence excludes Ana from the people who replied. The second confirms that Ana replied and adds Petro. Krom alone does not encode “minus” or “plus”; the surrounding clause supplies that operation.
Exception after a positive total
With ĉiuj, ĉio, tuta, or another expression covering a whole set, krom normally removes an exception:
La tuta raporto estas preta krom la lasta tabelo.
The entire report is ready except for the final table.
Ĉiuj fenestroj estis fermitaj krom tiu en la kuirejo.
All the windows were closed except the one in the kitchen.
The main positive statement does not apply to the krom item: the table is not ready; the kitchen window was not closed. The logic can be paraphrased as ĉiuj aliaj... sed ne....
Questions preserve the same possibility:
Ĉu ĉiuj krom Leo povas veni vendrede?
Can everyone except Leo come on Friday?
The question asks whether the ability applies to the whole set after Leo is removed.
Exception inside a negative statement
With neniu, nenio, ne, or sen, the excepted item is often the only positive case:
Neniu krom la deĵoranta flegisto rajtas eniri tiun ĉambron.
No one except the nurse on duty may enter that room.
Mi aŭdis nenion krom la pluvo kontraŭ la fenestroj.
I heard nothing except the rain against the windows.
The nurse may enter; the rain was heard. The negative statement applies to everyone or everything else, not to the exception.
— Kiu sciis pri la ŝanĝo? — Neniu krom la projektestro.
— Who knew about the change? — No one except the project manager.
English speakers sometimes add an extra ne because the exception feels negative. Do not: the negative correlative already establishes the negative domain.
Addition with ankaŭ, ankoraŭ, or eĉ
Additive krom states that the separated item participates and then adds another fact or participant. Ankaŭ is the clearest signal:
Krom la salato, ni mendis ankaŭ supon kaj panon.
Besides the salad, we also ordered soup and bread.
Krom labori plentempe, ŝi ankaŭ studas inĝenierarton vespere.
Besides working full-time, she also studies engineering in the evening.
Both the salad and the additional food were ordered; both working and studying are true. Ankoraŭ and eĉ can similarly reinforce addition.
Krom la direktoro venis eĉ tri membroj de la estraro.
Besides the director, even three board members came.
When the arithmetic matters, include an overt additive marker. Krom Ana venis Petro can be interpreted from context, but Krom Ana, ankaŭ Petro venis prevents the reader from briefly considering an exception reading.
Exception versus replacement
Krom and anstataŭ produce different sets:
Krom kafo ni mendis ankaŭ teon.
Besides coffee, we also ordered tea.
Anstataŭ kafo ni mendis teon.
Instead of coffee, we ordered tea.
Additive krom keeps the coffee and adds tea. Anstataŭ removes coffee and substitutes tea. Exceptive krom can remove an item from a broader total, but it does not say that another item takes its role. See Anstataŭ for replacement and role inheritance.
Infinitives and clauses
Krom is one of the established prepositions that naturally occurs before an infinitive:
Li faris nenion krom plendi pri la vetero.
He did nothing except complain about the weather.
Krom ripari biciklojn, ŝi ankaŭ gvidas senpagajn metiejojn.
Besides repairing bicycles, she also leads free workshops.
The main subject normally controls the infinitive: li complains; ŝi repairs and teaches. When a full clause with its own subject is needed, use krom tio, ke...:
Krom tio, ke la ĉambro estas malgranda, ĝi ankaŭ ricevas tre malmulte da lumo.
Besides the fact that the room is small, it also gets very little light.
Here krom tio is additive. In another polarity it can introduce an exception; once again, the larger construction determines the reading.
Complement role and case
Like anstataŭ, krom mainly says “set this apart” and may leave the separated item's grammatical role implicit. Usually no extra marking is needed:
Mi parolis kun ĉiuj krom Lea.
I spoke with everyone except Lea.
Context readily supplies kun Lea. If competing roles could be confused, repeat the preposition:
La komisiono sendis la decidon al ĉiuj kandidatoj krom al Nora.
The committee sent the decision to every candidate except Nora.
The repeated al makes Nora an excepted recipient rather than a person excepted from the subject group.
Accusative -n can exceptionally preserve an understood object role, but it is usually unnecessary after krom. Compare Krom Vilhelmo, ankaŭ Petro invitis Paŭlon (Vilhelmo is another inviter) with Krom Vilhelmon, Petro invitis ankaŭ Paŭlon (Vilhelmo is another invitee). Prefer fuller wording when the contrast would make a reader stop.
Kroma and krome are only additive
Derived kroma means additional or extra; krome means additionally, moreover. They never express exception:
Por matenmanĝo oni devas pagi kroman kotizon.
An additional fee must be paid for breakfast.
La apartamento estas hela; krome, ĝi havas grandan balkonon.
The apartment is bright; moreover, it has a large balcony.
This asymmetry is genuinely lexical: the two-way ambiguity belongs to prepositional krom, while the derived adjective and adverb settled on the additive branch.
Polarity and scope
Negative additive sentences are logically possible but hard to process: Krom Petro, ankaŭ Karlo ne venis means neither Petro nor Karlo came. In normal prose, say Nek Petro nek Karlo venis. The rewrite names the total directly and avoids asking the reader to calculate addition inside negation.
Scope also matters when krom sits far from the quantified expression. Keep an exceptive phrase close to ĉiuj/neniu/ĉio, or use escepte de for an unmistakable exception. Use aldone al for unmistakable addition.
Escepte de unu mallonga paŭzo, ni laboris seninterrompe ĝis la sesa.
Except for one short break, we worked continuously until six.
This is semantically equivalent to exceptive krom, but more explicit in dense (formal) prose.
Norm and usage
Both exceptive and additive krom are foundational and common across registers. The polarity patterns are stable, not recent innovations. Repeated prepositions and role-preserving case are accepted clarification strategies, though simple krom + nominative phrase is most frequent.
In (formal) and (academic) writing, ambiguity between inclusion and exclusion can change factual meaning. Use ankaŭ/aldone al for addition and escepte de/ĉiuj krom for exception. Everyday conversation relies more freely on context and intonation.
Common Mistakes
Confusing “besides” with physical “beside”
❌ Apud Marta, ankaŭ ŝia frato venos.
Incorrect for addition — apud expresses spatial proximity.
✅ Krom Marta, ankaŭ ŝia frato venos.
Besides Marta, her brother will also come.
Adding accusative to an excepted subject
❌ Ĉiuj krom Martan subskribis la peticion.
Incorrect — Marta is an excepted subject, so she remains nominative.
✅ Ĉiuj krom Marta subskribis la peticion.
Everyone except Marta signed the petition.
Adding a second negator to a negative correlative
❌ Neniu ne venis krom Marta.
Incorrect — neniu already makes the clause negative.
✅ Neniu venis krom Marta.
No one came except Marta.
Using kroma for an exception
❌ La tuta teksto estas ĝusta, kroma unu frazo.
Incorrect — kroma means additional, not except.
✅ La tuta teksto estas ĝusta, krom unu frazo.
The whole text is correct except for one sentence.
Key Takeaways
- Krom sets an item apart; the surrounding polarity determines exception or addition.
- A positive total plus krom excludes; a negative total plus krom leaves a positive exception.
- Ankaŭ, ankoraŭ, and eĉ make the additive reading explicit.
- Repeat a preposition or preserve case only when the separated grammatical role needs clarification.
- Kroma and krome are always additive.
