Questions & Answers about Tämä huone on valoisa.

Why is there no word for “the” or “a” in Tämä huone on valoisa?
Finnish does not use articles like “the” or “a.” Definiteness or indefiniteness is understood from context or indicated with demonstratives such as tämä (“this”) or se (“that”). In your sentence, tämä makes it clear you’re talking about a specific room.
What does Tämä mean, and how is it different from Tuo or Se?

Tämä is the nominative singular form of the demonstrative pronoun meaning “this” (something close to the speaker).

  • Tuo means “that” (something farther from the speaker).
  • Se can mean “that,” “it,” or act like a generic “the.”
    You use tämä here because you mean this particular room.
Why is huone in the basic (nominative) form and not another case?
The verb on (“is”) is a copula. In Finnish, both the subject and its predicate complement after a copula remain in the nominative case. Since huone is the subject, it stays nominative singular.
What part of speech is valoisa, and why is it also nominative singular?
Valoisa is a descriptive adjective formed with the suffix -isa (meaning “having the quality of…”). After a copula like on, adjectives are predicative and agree with the subject in case and number, so here it stays nominative singular.
Why does the adjective valoisa come after the verb on instead of directly before huone?
In Finnish, predicative adjectives normally follow the copula verb. So you say huone on valoisa (“the room is bright”). If you put valoisa before huone without a verb, it becomes an attributive adjective: valois a huone (“a bright room”), and you’d then need no copula.
How would you ask “Is this room bright?” in Finnish?

Turn on into a question by adding the question particle -ko/-kö and swapping subject and verb order:
Onko tämä huone valoisa?

How do you say “This room is not bright”?

Use the negative auxiliary verb ei in the third‐person singular, plus the main verb stem ole- with no personal ending, then the adjective:
Tämä huone ei ole valoisa.

How do you form the comparative “brighter” in Finnish?

Change valoisa to its comparative valoisampi (adjective + -mpi). The sentence stays otherwise the same:
Tämä huone on valoisampi.
To compare with another room, add “than…”:
Tämä huone on valoisampi kuin tuo huone.

How do you decline the adjective valoisa in other cases?

Stem: valoisa-

  • Nominative sg. valoisa
  • Genitive sg. valoisan
  • Partitive sg. valoisaa
  • Nominative pl. valoisat
  • Genitive pl. valoisten or valoisaiden
    … and so on following the standard adjective declension pattern.
