Question 1

Why is Portaikko in the nominative case here and not marked in some other way?

Accepted Answer

Portaikko is the subject of the sentence (“the staircase” that “looks” a certain way). In Finnish, the subject of a clause is in the nominative case. There is no article (“a/the”) in Finnish, so Portaikko simply stands for “a staircase” or “the staircase,” depending on context.

Question 2

Why is the adjective puhtaalta used instead of the base form puhdas?

Accepted Answer

In Finnish, when you say something “looks/appears” a certain way with näyttää, the adjective complement must be in the so-called -lta (adessive of resemblance) case. You cannot say Portaikko näyttää puhdas; you need Portaikko näyttää puhtaalta to mean “The staircase looks clean.”

Question 3

How exactly is puhtaalta formed from puhdas?

Accepted Answer

1. Start with the adjective stem puhda- (the -s drops before a consonant).  
2. Add the -lta ending: puhda + lta → puhdal(t)a.  
3. Apply Finnish consonant assimilation and vowel lengthening:  
   - d + l → t + l  
   - The preceding vowel a lengthens to aa  
   Result: puhtaalta.

Question 4

What is the literal meaning or function of the -lta case here?

Accepted Answer

This -lta ending is often called the “adessive of resemblance” (or simply the “-lta case”). It expresses appearance or resemblance, equivalent to English “like” or “as if.” So puhtaalta literally conveys “as if (it is) clean.”

Question 5

Can I change the word order and say Puhtaalta näyttää portaikko?

Accepted Answer

Yes. Finnish has fairly free word order for emphasis.  
– Portaikko näyttää puhtaalta. (Neutral)  
– Puhtaalta näyttää portaikko. (Emphasizes how it looks—“Clean, that staircase looks.”)

Question 6

How would you make this sentence negative?

Accepted Answer

Negate näyttää with ei, and the complement stays in -lta:  
Portaikko ei näytä puhtaalta.  
“That staircase does not look clean.”

Question 7

How do you say the same thing if there are multiple stairs?

Accepted Answer

Use the plural forms for subject, verb, and the -lta adjective:  
Portaat näyttävät puhtailta.  
“(The) stairs look clean.”

Question 8

Could I also say Portaikko näyttää olevan puhdas?

Accepted Answer

Yes. That’s another way to express “The staircase seems to be clean.” Here you use the -kse infinitive of olla (to be):  
näyttää + olevan + adjective → “appears to be …”  
It’s slightly more formal or explicit.

Question 9

When näyttää means “to show” (as in “show someone something”), does it still take -lta?

Accepted Answer

No. That’s a different (transitive) meaning of näyttää (“to display, to show”). In that sense you use a direct object in the accusative (or partitive), e.g.  
Näytä minulle valokuva. (“Show me the photo.”)  
Here there is no -lta on the object.
