Pinta on epätasainen.

Pinta means surface in this sentence.

It can refer to the outer layer or outside of something, such as:

• the surface of a table
• the surface of a road
• the surface of water
• the skin or outer coating of an object

So Pinta on epätasainen means The surface is uneven or The surface is irregular.

Finnish does not have articles like the or a/an.

So:

• pinta can mean surface, a surface, or the surface
• the exact meaning depends on context

In English, you need an article, but in Finnish you usually do not.

On means is.

It is the third-person singular form of the verb olla, which means to be.

Some forms of olla:

• minä olen = I am
• sinä olet = you are
• hän on = he/she is
• se on = it is
• ne ovat = they are

So:

• Pinta on epätasainen = The surface is uneven

Epätasainen means uneven, not level, or irregular.

It is built from:

• epä- = an un-/non-/not- prefix
• tasainen = even, level, smooth, steady

So epätasainen literally means something like not even or not level.

Depending on context, it could describe:

• a rough road
• an irregular surface
• a bumpy floor
• something not flat or smooth

Yes, epätasainen is an adjective.

In this sentence, it is a predicate adjective: it comes after on and describes the subject pinta.

Finnish adjectives do not always agree in number and case the same way English learners might expect. Here:

• pinta is singular nominative
• the predicate adjective is also in its basic dictionary form: epätasainen

So the structure is:

• pinta = subject
• on = is
• epätasainen = uneven

This is very similar to English: The surface is uneven.

This is the normal Finnish word order for a basic statement:

subject + verb + complement

So:

• Pinta = subject
• on = verb
• epätasainen = complement/adjective describing the subject

This is the most neutral way to say it.

Finnish word order is more flexible than English, but this order is the standard one for a simple statement.

Yes, but it means something slightly different in structure.

• epätasainen pinta = an uneven surface / the uneven surface
• Pinta on epätasainen = The surface is uneven

So:

1. Epätasainen pinta
   This is a noun phrase: adjective + noun.

2. Pinta on epätasainen
   This is a full sentence: noun + verb + adjective.

English works the same way:

• uneven surface
• the surface is uneven

A rough pronunciation guide is:

e-pä-ta-sai-nen

A few helpful points:

• ä is not the same as English a
• ai is a diphthong, something like the vowel sound in English eye
• stress in Finnish is almost always on the first syllable

So the stress is on e:

• Epätasainen

A rough English-style approximation might be:

• EH-pae-tah-sigh-nen

But the Finnish vowels should be kept clear and pure, not reduced as much as in English.

In Pinta on epätasainen, the adjective is used predicatively:

• it comes after the verb on
• it tells you what the surface is like

In epätasainen pinta, the adjective is used attributively:

• it comes before the noun
• it directly modifies the noun

So:

• Pinta on epätasainen = sentence
• epätasainen pinta = noun phrase

This distinction is very useful in Finnish, just as it is in English.

Yes, sometimes pinta can also be used in more abstract or extended senses, depending on context.

For example, it can refer to:

• the surface of water
• the surface level of something
• outward appearance in some expressions

But in a sentence like Pinta on epätasainen, the most natural meaning is usually a literal physical surface.

It could be correct in some contexts, but it is less neutral.

• Pinta on epätasainen = neutral, general statement
• Se pinta on epätasainen = That surface is uneven or that particular surface is uneven

Adding se makes it more specific or contrastive.

So if you are pointing at one surface among several, Se pinta on epätasainen could make sense. But by itself, the simpler and more natural sentence is Pinta on epätasainen.

The plural would be:

Pinnat ovat epätasaisia.

Word by word:

• pinnat = surfaces
• ovat = are
• epätasaisia = uneven

Here you can see both the noun and the adjective change in the plural.

So:

• Pinta on epätasainen = The surface is uneven
• Pinnat ovat epätasaisia = The surfaces are uneven

The most direct meaning is uneven.

That said, in real contexts, English might sometimes translate it as:

• uneven
• irregular
• not level
• sometimes even rough, if the surface is bumpy or not smooth

But rough is not always the best one-to-one translation. Epätasainen focuses more on the idea that the surface is not even or level.

Pinta is in the nominative singular, which is the basic dictionary form.

In this sentence it is the subject, so nominative is exactly what you would expect.

The basic pattern is:

• subject in nominative
• verb on
• adjective describing the subject

So pinta is in the normal subject form.

Yes, absolutely.

Pinta on epätasainen is a fully complete and natural Finnish sentence.

It has everything needed:

• a subject: pinta
• a verb: on
• a complement: epätasainen

So even though it is short, it is grammatically complete and idiomatic.
