Pogoda ma wpływ na bezpieczeństwo.

In Polish, mieć wpływ na literally means to have an influence on and is a very common, natural expression.

So:

• Pogoda ma wpływ na bezpieczeństwo. = Weather has an influence on safety.

You could also say:

• Pogoda wpływa na bezpieczeństwo. = Weather influences safety.

Both are correct. The version with ma wpływ na is slightly more noun-based, while wpływa na is more directly verbal.

Bezpieczeństwo is in the accusative case here.

That is because the phrase wpływ na requires na + accusative when it means influence on something.

So:

• na bezpieczeństwo = on safety

This is one of those combinations you often just learn as a set phrase:

• mieć wpływ na coś = to have an influence on something

Because na can take different cases depending on meaning.

With location, na often takes the locative:

• na stole = on the table

With direction/result/target, na often takes the accusative:

• iść na stół = to go onto the table
• mieć wpływ na coś = to have an influence on something

In this sentence, safety is the target of the influence, so Polish uses na bezpieczeństwo.

Because wpływ is the direct object of ma and, for this noun, the accusative singular looks the same as the nominative singular.

• wpływ is a masculine inanimate noun.
• Masculine inanimate nouns often have the same form in nominative and accusative singular.

So:

• ma wpływ = has influence / has an influence

Even though it is the object, the form stays wpływ.

Here are the genders:

• pogoda — feminine
• wpływ — masculine
• bezpieczeństwo — neuter

This matters because gender affects adjective forms, past tense forms, and some other parts of grammar.

For example:

• dobra pogoda = good weather
• duży wpływ = big influence
• publiczne bezpieczeństwo = public safety

Polish does not have articles like the and a/an.

So Pogoda ma wpływ na bezpieczeństwo can mean:

• Weather has an influence on safety
• The weather has an influence on safety

Which one sounds best in English depends on context, but Polish does not mark that difference with articles.

Yes, Polish word order is more flexible than English because case endings show grammatical relationships.

The neutral order here is:

• Pogoda ma wpływ na bezpieczeństwo.

But other orders are possible for emphasis, for example:

• Na bezpieczeństwo pogoda ma wpływ.
• Wpływ na bezpieczeństwo ma pogoda.

These versions are more marked and would sound more emphatic or stylistic. For a learner, the original order is the safest and most natural.

Yes, wpływ is a tricky word for English speakers.

A rough guide:

• w in Polish sounds like English v
• ł sounds like English w
• y is a vowel that does not exist exactly in English; it is a short, central sound

So wpływ is roughly like vpwihv as one compact word, though that is only approximate.

The cluster at the beginning, wpł-, is normal in Polish but unusual for English speakers. It helps to build it slowly:

• w
• wp
• wpł
• wpływ

Yes, pogoda is singular here and that is normal.

In Polish, pogoda usually means weather as a general idea, much like English weather, which is also normally uncountable/singular in meaning.

So:

• Pogoda jest dobra. = The weather is good.
• Pogoda ma wpływ na bezpieczeństwo. = Weather affects safety.

You would not normally use a plural here.

Yes. Bezpieczeństwo can often be translated as safety or security, depending on context.

For example:

• road conditions, accidents, driving → safety
• crime, protection, national issues → security

So the exact English translation depends on the situation. The Polish noun itself is broader.

The dictionary forms are:

• pogoda — weather
• mieć — to have
  
  • here it appears as ma = has
• wpływ — influence, impact
• na — on, onto
• bezpieczeństwo — safety, security

So grammatically, the structure is:

• Pogoda — subject
• ma — verb
• wpływ — object
• na bezpieczeństwo — prepositional phrase showing what is affected

Definitely. It is a very useful set expression.

You can reuse it with many nouns:

• Stres ma wpływ na zdrowie. = Stress has an influence on health.
• Cena ma wpływ na decyzję. = Price influences the decision.
• Rodzina ma wpływ na dziecko. = Family has an influence on the child.
