Questions & Answers about Powódź była tak duża, że woda zalała rynek.
How does the tak ..., że ... structure work in this sentence?
It translates to "so ... that ...". The word tak intensifies the adjective duża (big), and the conjunction że (that) introduces the result or consequence of that intensity. You will use this exact structure whenever you want to express that a state was so extreme that it caused a specific outcome.
Could we use na tyle ..., że ... instead of tak ..., że ... here?
Grammatically yes, but the nuance changes. If you say Powódź była na tyle duża, że..., it translates to "The flood was big enough that...". While tak ..., że ... emphasizes the extreme intensity of the flood, na tyle ..., że ... simply states that the flood reached the required threshold to cause the result.
The noun powódź ends in a consonant. Why does it take the feminine verb była and the feminine adjective duża?
Although most Polish nouns ending in a hard consonant are masculine, powódź is a feminine noun. A large group of nouns ending in soft consonants like -dź, -ć, or -ś (such as odpowiedź or miłość) are feminine. Because of this, any adjectives and past-tense verbs describing them must take feminine forms.
