In Czech, almost every word for a person comes in two flavours: a masculine form and a feminine one derived from it. A male teacher is učitel; a female teacher is učitelka. This systematic feminisation is called přechylování, and unlike in English — where "actress" and "waitress" are fading and "doctor" covers everyone — in Czech it is grammatically expected and near-obligatory for professions, roles, nationalities and surnames. Leaving it out does not sound progressive; it sounds broken.
For an English speaker this is one of the more alien corners of the language, both because English has shed most of its feminine-marked nouns and because the surname suffix -ová is genuinely surprising the first time you meet a "Mrs Nováková". This page lays out the main suffixes, the consonant changes they trigger, and why Czech insists on them.
Why Czech feminises so thoroughly
The deep reason is grammatical gender agreement. A Czech sentence has to agree its verb, adjectives and pronouns with the gender of the subject. If you say "the teacher arrived," the past-tense verb itself is gendered: učitel přišel (he) versus učitelka přišla (she). So the noun's gender is not a social nicety — it is load-bearing syntax. To talk about a woman at all, Czech needs a feminine noun to anchor the agreement.
Naše nová učitelka přišla pozdě, protože jí ujela tramvaj.
Our new (female) teacher arrived late because she missed the tram.
Náš nový učitel přišel pozdě, protože mu ujela tramvaj.
Our new (male) teacher arrived late because he missed the tram.
Notice how přišla / přišel and náš / naše all flip with the noun. You cannot keep the masculine učitel and just mean a woman — the rest of the sentence would clash.
The main suffix: -ka
By far the most productive feminine suffix is -ka. It attaches to a huge range of masculine person-nouns: professions, nationalities, group memberships.
| Masculine | Feminine (-ka) | English |
|---|---|---|
| učitel | učitelka | teacher |
| student | studentka | student |
| doktor | doktorka | doctor |
| kamarád | kamarádka | friend |
| Američan | Američanka | American |
| soused | sousedka | neighbour |
Moje sousedka je doktorka v nemocnici na Vinohradech.
My (female) neighbour is a doctor at the hospital in Vinohrady.
Je výborná studentka, na zkoušce dostala jedničku.
She's an excellent student; she got top marks in the exam.
Watch for consonant softening before -ka. A final -k, -c or -ec often changes: Čech ("a Czech man") → Češka (the ch softens to š); cizinec ("foreigner") → cizinka, with the fleeting -e- and the c giving way.
Je Češka, ale vyrostla v Kanadě a mluví líp anglicky.
She's Czech, but she grew up in Canada and speaks better English.
The suffix -yně
A second, slightly more formal suffix is -yně. It tends to appear where -ka would be awkward or where tradition fixed it — often after -l, -c or with certain roots.
| Masculine | Feminine (-yně) | English |
|---|---|---|
| přítel | přítelkyně | friend; girlfriend |
| žák | žákyně | pupil |
| vědec | vědkyně | scientist |
| kolega | kolegyně | colleague |
| průvodce | průvodkyně | guide |
Note that přítelkyně carries the extra meaning "girlfriend" alongside "female friend" — context decides. And vědec → vědkyně shows a stem change: the -ec drops and the c is lost before -kyně.
Moje přítelkyně pracuje jako vědkyně v laboratoři.
My girlfriend works as a scientist in a lab.
Naše průvodkyně po hradě mluvila čtyřmi jazyky.
Our (female) guide around the castle spoke four languages.
The surname suffix: -ová
This is the one that startles learners. Czech women's surnames are systematically derived from the masculine family name, most commonly with -ová.
| Man's surname | Woman's surname |
|---|---|
| Novák | Nováková |
| Svoboda | Svobodová |
| Dvořák | Dvořáková |
| Černý | Černá |
Two important wrinkles:
First, surnames that are already adjectives (like Černý, "black") feminise as adjectives do, not with -ová: Černý → Černá, Veselý → Veselá.
Second — and this is the structurally fascinating part — an -ová surname declines like an adjective, not like a noun. So Mrs Nováková changes her ending through the cases exactly as a feminine adjective would:
| Case | Form |
|---|---|
| Nominative (subject) | Nováková |
| Genitive (of) | Novákové |
| Dative (to/for) | Novákové |
| Accusative (object) | Novákovou |
| Instrumental (with/by) | Novákovou |
Paní Nováková učí naši dceru matematiku.
Mrs Nováková teaches our daughter maths.
Tu zprávu musíš poslat paní Novákové ještě dnes.
You have to send that message to Mrs Nováková today.
Mluvil jsem s paní Novákovou o tom problému.
I spoke with Mrs Nováková about that problem.
In those three sentences the surname moves Nováková → Novákové → Novákovou purely by adjective rules. A man's surname, Novák, declines as a noun instead (Nováka, Novákovi, s Novákem).
Foreign female surnames: the live debate
Traditionally Czech even Czechised foreign women's surnames: the German chancellor became Merkelová, the singer Adele would be referred to in older usage with the suffix attached. This is consistent with the grammar — an -ová form is declinable and slots into Czech sentences cleanly, whereas an undeclined foreign name fights the case system.
But it is now genuinely contested. A 2021 change to the law made it easier for women in the Czech Republic to register their surnames without the -ová ending if they choose, and there is ongoing public debate about whether foreign names should be modified at all. So this is one area where the "rule" is in flux: traditional and journalistic usage still leans heavily toward Merkelová, Thunbergová, but you will increasingly see the unmodified forms, and individual women's preferences are now legally protected.
V novinách psali o kancléřce Merkelové a jejím nástupci.
The papers wrote about Chancellor Merkel and her successor. (traditional Czechised form)
Některé ženy dnes dávají přednost příjmení bez koncovky -ová.
Some women today prefer a surname without the -ová ending.
Common mistakes
❌ Moje sestra je dobrý učitel.
Incorrect — a woman is an učitelka, and the adjective must be feminine too.
✅ Moje sestra je dobrá učitelka.
My sister is a good teacher.
❌ Mluvil jsem s paní Novák.
Incorrect — a Czech woman's surname takes -ová and then declines; here it should be the instrumental Novákovou.
✅ Mluvil jsem s paní Novákovou.
I spoke with Mrs Nováková.
❌ Dal jsem to paní Nováková.
Incorrect — the -ová surname declines like an adjective; the dative is Novákové, not the unchanged Nováková.
✅ Dal jsem to paní Novákové.
I gave it to Mrs Nováková.
❌ Je to Čechka a studuje medicínu.
Incorrect — 'a Czech woman' is Češka, with ch softening to š, not Čechka.
✅ Je to Češka a studuje medicínu.
She's Czech and studies medicine.
❌ Naše nová kolega přišla z Brna.
Incorrect — a female colleague is kolegyně, and the adjective must agree as feminine.
✅ Naše nová kolegyně přišla z Brna.
Our new (female) colleague came from Brno.
