Questions & Answers about Na této straně je zvuk lepší.

What does Na této straně je zvuk lepší literally mean word by word?

A very literal breakdown is:

• Na = on / at
• této = this
• straně = side
• je = is
• zvuk = sound
• lepší = better

So the sentence is literally:

On this side, the sound is better.

Depending on context, strana can mean side, but also sometimes page or party. Here it most naturally means side.

Why is it na této straně and not just tato strana?

Because after the preposition na, Czech usually changes the form of the following words according to case.

Here, na této straně is describing a location:
on this side / on this page / at this side

So Czech uses the locative case after na when it means location.

That is why:

• tato strana = this side (basic dictionary form, nominative)
• na této straně = on this side (locative after na)

Both této and straně are changed to match the locative.
