Questions & Answers about Kryptografia pomaga chronić poufne dane.
The word dane means "data", but doesn't it come from the verb dać (to give)?
Yes! Dane is historically the passive adjectival participle of dać, so it literally translates to "the given [things]". It has become the standard noun for "data" in Polish and is always plural. Because it retains its adjectival roots, it declines exactly like an adjective.
Why is poufne dane in the accusative case here instead of the genitive?
Chronić (to protect) is a standard transitive verb that takes its direct object in the accusative case when the sentence is positive. For non-masculine-personal plural nouns like dane, the accusative form is identical to the nominative. The genitive case would only take over if the verb were negated, such as nie chroni poufnych danych.
Could I use the perfective verb ochronić instead of the imperfective chronić?
The imperfective chronić is much more natural here because the sentence describes a continuous, general function of cryptography. Using the perfective ochronić would imply helping to complete a one-time, specific rescue of data from a single, immediate threat.
How would I apply the nie sposób structure from this lesson to say it's impossible to protect data without cryptography?
You would use nie sposób right before the infinitive: Bez kryptografii nie sposób chronić poufnych danych (Without cryptography, it's impossible to protect confidential data). Crucially, because nie sposób inherently acts as a negation, the direct object must flip from the accusative (poufne dane) to the genitive (poufnych danych).
