Hi! Do you mean words used only for male/female as in jobs? Yes, you can say zdravotní bratr, it means male nurse and you can't use it for a female nurse. This is probably one of rare cases where the word for male/female worker is completely different, because it uses the words brother/sister (bratr/sestra). Usually, we only add a different ending to the male version or the words have the same root at least. Examples of some male/female words for jobs: Kuchař/kuchařka - a Cook Číšník/číšnice - a waiter/waitress Soudce/soudkyně - a judge Lékař/lékařka - a doctor Herec/herečka - an actor/actress Překladatel/překladatelka - a translator Spisovatel/spisovatelka - a writer Policista/policistka - a cop Učitel/učitelka - a teacher Prodavač/prodavačka - a shop assistant This usually applies to other gendered words, not just jobs, for example: Útočník/útočnice - an attacker Student/studentka - a student Zloděj/zlodějka - a Thief Hope it helped a bit. If this isn't what you were asking for or you want more examples, you can send me a message and I will gladly help you :)

Hi! You can try the wiktionary. If you have the site in Czech language, you would be looking for the words dokonavé (perfektum) or nedokonavé (imperfektum). Many articles are written in English, too. Example: a search for the word "házet" shows it has an imperfective form. https://en.wiktionary.org/wiki/h%C3%A1zet

Hi Simo, can you copy it and paste to to your google? It should work that way. Thanks
