Questions & Answers about Из-за слабости и кашля терапевт сказала, что это может быть бронхит, а не обычная простуда.
Из-за means because of or due to.
It requires the genitive case, so the nouns after it change form:
- слабость → слабости
- кашель → кашля
So из-за слабости и кашля means because of weakness and cough.
A useful thing to remember: из-за often introduces a cause, and it frequently has a slightly negative flavor, which fits well here because these are symptoms.
They are different nouns, belonging to different declension patterns, so their genitive singular endings are different.
слабость is a feminine noun ending in -ость
- nominative: слабость
- genitive: слабости
кашель is a masculine noun
- nominative: кашель
- genitive: кашля
So both are in the same case, but they take different endings because they are different types of nouns.
