Evidenční známka není mikročip.

Není is the 3rd person singular present tense negative form of být (to be).

• je = is
• není = is not

So in this sentence, není means is not. Czech does not need a separate word like English not here; the negation is built into the verb form itself.

Czech does not have articles, so there is no direct equivalent of English a, an, or the.

So:

• mikročip can mean a microchip or the microchip
• the exact meaning depends on context

That is completely normal in Czech.

Both are in the nominative singular here.

• evidenční známka is the subject
• mikročip is the predicate noun after není

In simple identification/classification sentences with být (to be), Czech often uses the nominative:

• To je problém. = That is a problem.
• Pes není člověk. = A dog is not a human.

So Evidenční známka není mikročip. uses a very normal structure.

After být, Czech can sometimes use either the nominative or the instrumental for the predicate noun, depending on style and nuance.

Here, mikročip in the nominative is the most neutral and straightforward choice for simple identification:

• Evidenční známka není mikročip.

An instrumental form like mikročipem is not impossible in Czech generally, but it would sound less natural here for a basic definition-style statement. For a learner, the nominative version is the one to remember first.

No—this is a useful false friend to notice.

Czech evidence usually means records, registration, or official listing, not English evidence in the sense of proof.

So evidenční means something like:

• registration
• identification
• record-keeping

And známka has several meanings in Czech, such as:

• stamp
• mark
• grade
• tag/label in some contexts

So evidenční známka is something like an identification tag, registration label, or registration mark, depending on context.

Evidenční is an adjective, and it agrees with známka.

Here:

• známka is feminine singular nominative
• evidenční is also feminine singular nominative

Many Czech adjectives ending in -ní, -ční, or similar patterns have forms like evidenční. This ending is normal and does not mean it is plural.

So the phrase evidenční známka is a grammatically matching adjective + noun combination.

• známka is feminine
• mikročip is masculine inanimate

This matters because Czech nouns affect adjective agreement and other forms in the sentence.

For example, evidenční agrees with the feminine noun známka.
The verb není does not show gender here, so the gender difference is not visible on the verb.

The word order here is the most neutral one:

• Evidenční známka není mikročip.

Czech word order is fairly flexible, so other versions are possible for emphasis, but they change the focus or sound more marked.

For example:

• Mikročip to není. = It is not a microchip.
• Mikročipem to není. = another possible emphatic structure in a different style

For a basic statement, the original order is the best one to learn first.

A rough English-friendly pronunciation would be:

EH-vi-dench-nee ZNAAM-ka NEH-nee MEE-kro-chip

A few helpful points:

• Czech stress usually falls on the first syllable of each word.
• á and í are long vowels.
• č sounds like ch in chip.

So:

• evidenční → EH-vi-dench-nee
• známka → ZNAAM-ka
• není → NEH-nee
• mikročip → MEE-kro-chip

No. Známka is a very flexible Czech word, and its meaning depends a lot on context.

It can mean things like:

• stamp
• mark
• grade (in school)
• sign/indication
• tag/label in some contexts

So in evidenční známka, it should not automatically be understood as a postal stamp. The full phrase gives it the more specific meaning.
