Suffixes on Names, Initialisms, and Numerals: Contrasts and Learner Traps

The difficult cases in suffixing are not solved by a single “always use a hyphen” rule. Hungarian balances two principles: an ordinary word-like base takes endings directly, while an opaque, abbreviated, numerical, or otherwise protected base keeps a visible boundary. Pronunciation selects the suffix form; orthographic structure selects the attachment. Review the formation system and communicative uses before applying the diagnostics here.

Direct attachment versus a protective hyphen

Hungarian names normally take suffixes directly: Anna → Annával, Bálint → Bálinttal, Szabolcs → Szabolccsal. A foreign spelling also takes direct attachment when its ending is sufficiently transparent: Stockholm → Stockholmban, Amundsen → Amundsenről. Foreignness alone does not trigger a hyphen.

This matched pair shows the real contrast. Stockholm has a directly interpretable final spelling, whereas Glasgow ends in a spelling whose relationship to Hungarian pronunciation is not transparent, so Glasgow-ban protects the name with a hyphen.

A silent final letter produces the same contrast. Goethének attaches directly because the final e participates in the Hungarian inflected written form and lengthens to é. In Voltaire-é, however, the silent final e remains part of the protected French name and possessive -é follows a hyphen.

There is no universal shortcut based on the final letter e; the conventional pronunciation and the structure of the spelling must be known.

Assimilation without destroying the name

With -val/-vel, the v assimilates to a final consonant. On an ordinary Hungarian name this is written directly: Péterrel, Bálinttal. On a name with a silent ending, the hyphen separates the unchanged base from the assimilated suffix: Molière-rel. This gives a useful minimal contrast in architecture even though both spoken forms end with a long r sound.

A protection rule applies when a foreign proper name or Hungarian family name already ends in a doubled consonant and the suffix would begin with the same consonant: Mann-nak, Scott-tól, Grimm-mel, Kiss-sel. Hungarian given names form the crucial contrast: they simplify three identical consonant letters just like common nouns, so the standard form is Mariannal, not Mariann-nal.

Initialism, abbreviation, or ordinary word?

Capital initialisms and acronyms take hyphenated suffixes: MTA-tól, ENSZ-ben, ELTE-s. Harmony comes from pronunciation. A conventional abbreviation ending in a period keeps both the period and a suffixal hyphen: Bp.-en. A lowercase initialism that has become an ordinary lexical word can instead take direct endings: áfát, tajjal. The visually similar bases therefore belong to different orthographic classes.

Compare tv-ben with tévében. The first keeps the initialism and attaches -ben by hyphen; the second spells the letter names as an ordinary word and attaches directly. Both are current, but tévében is visually smoother in neutral running prose, while tv-ben is compact (informal) or space-saving.

Capitalization cannot be used alone as a foolproof algorithm: conventional lexicalized exceptions such as áfa must be learned. In (formal) and (academic) writing, follow the official name or the house style consistently.

What pronunciation contributes—and what it does not

Pronunciation controls harmony even when the written base contains no visible Hungarian vowel. BBC-vel follows the conventional pronunciation, whose final syllable contains a front vowel, so the suffix is front. MTA-tól is based on the conventional pronunciation of the abbreviation and takes the back form. A learner who chooses from the nearest printed character has no usable evidence.

Pronunciation does not license phonetic spelling of the base. ELTE-s may contain a lengthened vowel in speech, but the written acronym remains ELTE, not ELTÉ. The hyphen simultaneously preserves the base and displays the morphological boundary.

Cardinal figure, ordinal figure, or date?

Figures take suffixes with a hyphen: 4-et, 19-szer, 67-es. An ordinal figure before a noun carries a period: a 4. emelet. If that overt ordinal itself is suffixed, the period remains: a IV.-be jár. A suffixed calendar day is the crucial exception: május 5-én has no period before the suffix.

The two sentences are exact meaning equivalents in different graphic styles. Now compare the date:

The period in 5. says “ordinal used as an ordinal numeral.” In the established date forms 5-én, 5-e, 5-i, the suffix or ending itself marks the relationship, and the ordinal period is omitted. Outside the date construction, do not generalize this exception.

Information structure and register

Focus affects word order and emphasis, not suffix spelling. Contrastive nem az ELTE-n, hanem a BME-n keeps both institutional suffixes. Contrastive dates likewise remain nem 5-én, hanem 6-án.

In an official (formal) notice, abbreviations and figures are common because the referents are exact and space matters: A pályázatokat 2026. május 5-éig az MTA-nak kell benyújtani. In a friendly (informal) message, full words may sound less bureaucratic: Május ötödikéig küldd el nekem. The underlying morphology is the same; the choice of graphic base changes with genre.

Decision tree

1. Is the base written as an ordinary full word or a normal transparent name? Attach directly: Annával, Stockholmban.
2. Does a foreign base end in a silent letter or an unusual final letter group? Preserve it and use a hyphen: Molière-rel, Glasgow-ban.
3. Would suffixation create three identical consonant letters in a name? Simplify them in a Hungarian given name (Mariannal), but preserve a foreign proper name or Hungarian family name with a hyphen (Mann-nak, Kiss-sel).
4. Is it a capital initialism, a dotted abbreviation, or a figure? Use a hyphen: ENSZ-ben, Bp.-en, 12-t.
5. Is it an established lowercase lexicalized initialism or spelled-out letter name? Treat it as a word: áfát, tévében.
6. Which suffix variant is required? Say the base aloud; use its conventional pronunciation for harmony and assimilation.
7. Is the figure a calendar day with an ending? Write 5-én without an ordinal period. Otherwise preserve required ordinal punctuation: IV.-be.

Diagnostic exercise

Choose the standard form, then compare the explanation.

1. “with Mariann”: Mariannal or Mariann-nal?
2. “in Glasgow”: Glasgowban or Glasgow-ban?
3. “on May 5”: május 5.-én or május 5-én?
4. “with the BBC”: BBC-val or BBC-vel?
5. “VAT” as the object: áfa-t or áfát?

Answers: (1) Mariannal follows the simplification rule for Hungarian given names. (2) Glasgow-ban uses a hyphen because the foreign ending is orthographically opaque. (3) május 5-én is the special suffixed-date pattern, without a period. (4) BBC-vel follows the conventional pronunciation, which ends in a front vowel. (5) áfát treats lexicalized áfa as an ordinary word and lengthens final a.

Common Mistakes

Key Takeaways

The three independent decisions are meaning, pronunciation, and orthographic category. Meaning chooses the suffix, pronunciation chooses its harmonic form, and the written base determines direct attachment versus a protective hyphen; keeping those decisions separate prevents most errors on this page.
