One of the 8 common mistakes every Russian language learner makes according to Russia Beyond (2018). Including a “Word of warning: It takes a VERY long time to get accustomed to the stresses on Russian words At times, you’ll be confronted with a new word and have absolutely no idea how to pronounce it.’ No stress: this is going to help, and will speed things up.
Catalógus or catálogus? The latter is correct (traceable to the Greek), but no one looks strangely if you say catalógus. In Russian, emphasis is more important. It can determine both the pronunciation of a word (an stressed syllable sometimes sounds very different from an unstressed one) and its spelling.
You often have to deal with the latter when conjugating adjectives. ж, ц, ч, ш and щ only have an o if they are stressed; if not, e instead of o. That explains why you write хорóшее вино (good wine), but плохóе вино (bad wine).
In some words the emphasis determines their meaning. Духи́ is perfume, ду́хи are spirits. Мука́ is flour, му́ка is suffering (pain, torment). Beware in fancy restaurants or at the jeweler’s. Я пла́чу is I cry, я плачу́ I pay.
Dutch also has such homographs (see Wikpedia and Onze Taal); with a little imagination, the homographer is one himself. More Russian омографы at RussianPodcast.eu.
In Czech and Finnish words the emphasis is by default on the first syllable, and in French words on the last. Polish and Swahili are also childishly simple in this respect, with their stress always on the second-to-last syllable.
Russian is different. The place of the stress is often difficult to predict, and it can already shift when the word becomes plural. As in сло́ва and слова́ (word(s)) or окно́ and о́кна (window(s)).
Several guidelines offer guidance. The simplest is that in words with an ë in them (see The letter ë) the stress always falls on that letter. And often (not always) on the last syllable in neuter words ending in -o, as in кольцо́ (ring) and лицо́ (face). The last syllable of feminine words ending in -a is usually stressed when that word has two syllables, as in мечта́ (dream) and рука́ (hand).
