is and sem: Contrasts and Learner Traps

The choice between is, sem, and their neighbors depends on discourse, not on a one-word English gloss. Use is to add a positive alternative, sem to add a negative one, and még ... is/sem when the alternative is noteworthy on a scale. Use nem for plain denial, csak for exclusion, and mégis/mégsem for a result contrary to expectation. The forms page gives the construction inventory; this page tests the boundaries.

Additive is versus coordination with és

És joins expressions or propositions. Is marks one constituent as an addition to an alternative already accessible. They can occur together because they do different jobs.

The first sentence simply coordinates two names. The second treats Bence’s attendance as established and adds Réka. English and and too show the same distinction, but English often places too at the end; Hungarian places is immediately after its host.

These are a useful scope pair. Réka is adds Réka to other bringers. Süteményt is adds cake to other things Réka brings. The English translations may look nearly identical without context, but the Hungarian placement makes the intended alternative visible.

Additive is versus exclusive csak

Is expands a relevant set; csak restricts it. This semantic opposition also interacts differently with Hungarian verbal prefixes.

In the additive sentence, Réka is does not occupy the ordinary exclusive focus position, and felhívott remains together. In the exclusive sentence, csak Réka is immediately preverbal focus and the prefix follows the verb: hívott fel. This is a practical diagnostic, not merely punctuation.

Plain addition versus scalar “even”

Plain X is normally means that X is another relevant case. Még X is ranks X as unexpectedly strong, weak, unlikely, or otherwise extreme.

The second sentence can sound dismissive if it presents the intern as least capable. Scalar particles therefore communicate stance about a person, not only truth conditions. Choose the scale responsibly.

The first adds “address” to information not known. The second treats knowing a name as a minimal expectation and denies even that. In careful speech and writing, még is the clearest signal that the intended reading is scalar.

Sem versus simple nem

Nem denies a predicate or constituent. Sem adds an item to a negative set.

The sem sentence normally needs a context in which someone else is not coming or another relevant possibility has failed. Without such common ground, plain nem is the neutral choice.

Constituent negation differs again:

Nem Anna rejects Anna and corrects the identity. Anna sem includes Anna in a negative pattern. This distinction repairs a frequent English-speaker error: English not Anna either can obscure whether the speaker is correcting a name or extending a negative list.

Negative concord is not logical double negation

Hungarian negative indefinites require clause-level negation. Both Senki nem jött and Senki sem jött are standard ways to say “Nobody came”; the negative forms cooperate rather than canceling.

The second can sound slightly more emphatic or stylistically balanced, but sem after a negative indefinite does not necessarily contribute a separate “either” proposition. Postverbally, nem remains visible:

There is one semantic negation despite nem, senkinek, and semmit. See negative concord for the full distribution.

Sem versus se

Traditional careful usage aligns sem with indicative negation and se with the imperative/optative negative series otherwise represented by ne. Contemporary informal speech often extends se into indicative contexts.

In everyday conversation (informal), Tegnap se hívtak vissza is widespread and natural. In edited prose (formal), sem is the conservative default with an indicative verb. With a negative command, se is the dependable choice: Te se menj! Do not present every spoken se as an error; it is register-sensitive variation.

Sem ... sem versus simple alternatives

Paired sem ... sem rejects every listed alternative. Vagy ... vagy presents alternatives without rejecting them.

When the pair follows a negated verb, the order changes but the meaning remains negative:

In ordinary speech (informal), se levest, se salátát is common. Formal writing often favors the full sem ... sem. Each alternative must carry its own particle; a single initial sem does not normally coordinate the whole pair.

Concession with is versus resultative mégis

Concessive is stays inside the subordinate expression that names an admitted obstacle. Mégis belongs to the main assertion and means “nevertheless/after all.”

The first treats rain as a possible or admitted condition. The second asserts rain as fact and presents departure as contrary to the expectation it creates.

Negative mégsem likewise differs from scalar még ... sem:

Writing the forms together or separately reflects a real lexical difference. Mégsem is a single concessive-result particle; még Péter sem surrounds a scalar associate.

Information structure and intonation

An is/sem phrase has a visible host, but context and prosody can widen the interpreted addition. Compare a noun host with a verbal-prefix host:

The first adds the letter to other sent material. The second associates is with the sending event and often confirms that an expected step actually happened. In speech, stress falls on the relevant lexical material; is itself is normally unstressed. Overstressing it in imitation of English emphatic TOO can make the sentence sound unnatural.

Decision tree

1. Are you simply denying the proposition with no additive background? Use nem.
2. Are you adding a positive participant, object, time, or event? Put is after that host.
3. Are you adding a negative alternative? Put sem after the host and use the required negative-concord pattern.
4. Is the added alternative surprising on a scale? Use még ... is or még ... sem.
5. Are two alternatives both rejected? Mark both with sem ... sem; in prohibitions, use se ... se.
6. Is an obstacle admitted inside a subordinate frame? Use concessive is.
7. Does the main result defeat an expectation? Use mégis or negative mégsem.

Diagnostic exercise

1. Context: Bence ordered tea; Réka ordered tea too. Choose Réka is teát kért because Réka is the added participant.
2. Context: Réka ordered coffee and tea. Choose Réka teát is kért because tea is the added object.
3. Context: Anna is the only person not attending. Choose Anna nem jön; there is no previous negative alternative to add.
4. Context: Bence is not attending, and Anna is not attending either. Choose Anna sem jön.
5. “Although it is expensive, I will buy it.” Choose Bár drága is, megveszem; the obstacle is inside the concessive phrase.
6. “It is expensive, but I will buy it nevertheless.” Choose Drága, mégis megveszem; the main decision defeats an expectation.

Common Mistakes

Key Takeaways

• Is expands an alternative set; csak restricts one.
• Plain is/sem is additive; még ... is/sem makes the scalar “even” reading explicit.
• Nem denies; sem adds negatively; Hungarian negative concord does not create two logical negations.
• Se is regular in prohibitions and widespread in informal indicative speech; sem is safest in edited indicative prose.
• Concessive is, mégis, and mégsem occupy different structures and express different expectations.
