Basic Conjunctions in Finnish

Overview

Conjunctions are the glue that holds sentences together, and you will need them from the very beginning of your A1 Finnish studies. Finnish basic conjunctions work similarly to their English counterparts — they connect words, phrases, and clauses. The most essential ones are ja (and), mutta (but), tai (or), vai (or, in questions), and koska (because).

One distinctive feature of Finnish is the distinction between tai and vai — both mean "or," but they are used in different contexts. Tai is for statements and open-ended alternatives, while vai is for questions where the asker presents specific choices. This distinction does not exist in English and is a common stumbling point for learners.

Mastering these basic connectors will immediately make your Finnish sound more natural and allow you to express more complex ideas, even with limited vocabulary.

How It Works

Coordinating conjunctions

Finnish	English	Usage
ja	and	Connects similar elements
mutta	but	Introduces contrast
tai	or	Alternatives (statements)
vai	or	Alternatives (questions)
sekä...että	both...and	Emphatic "and"
eli	that is / or	Clarification

Subordinating conjunctions (basic)

Finnish	English	Usage
koska	because	Reason
kun	when	Time
jos	if	Condition
että	that	Reported speech/complement
vaikka	although	Concession

Tai vs. Vai

Context	Conjunction	Example
Statement	tai	Juon kahvia tai teetä. (I drink coffee or tea.)
Open question	tai	Mitä haluat, kahvia tai teetä? (What do you want, coffee or tea?)
Choice question	vai	Haluatko kahvia vai teetä? (Do you want coffee or tea?)

Use vai when presenting a closed set of choices (A or B?) and tai for open alternatives.

Word order with conjunctions

Coordinating conjunctions do not change word order:

• Puhun suomea ja englantia. (I speak Finnish and English.)

Subordinating conjunctions introduce a subordinate clause where the verb typically goes to the end or stays in normal position:

• En tule, koska olen sairas. (I'm not coming because I am sick.)
• Kerro, kun olet valmis. (Tell me when you are ready.)

Common Mistakes

Using "tai" instead of "vai" in choice questions

• Wrong: Haluatko kahvia tai teetä?
• Right: Haluatko kahvia vai teetä?
• Why: When you present a specific either/or choice in a question, use vai. Tai implies open alternatives or is used in statements.

Putting "koska" at the beginning of standalone answers

• Wrong: Koska olen sairas. (as a complete sentence)
• Right: Siksi, koska olen sairas. or combine with the main clause.
• Why: While this is becoming more acceptable in casual speech (as in English "Because I'm sick"), traditional Finnish grammar treats koska as requiring a main clause.

Forgetting "että" in indirect speech

• Wrong: Hän sanoi tulee myöhemmin.
• Right: Hän sanoi, että tulee myöhemmin.
• Why: Finnish uses että to introduce reported speech clauses, similar to English "that."

Practice Tips

1. Sentence combining: Take pairs of simple sentences and connect them with different conjunctions. Example: Olen väsynyt. Menen nukkumaan. → Olen väsynyt, ja menen nukkumaan. / Menen nukkumaan, koska olen väsynyt.
2. Tai/vai sorting: Write 10 sentences with "or" and decide whether each needs tai or vai. The rule: if it is a yes/no choice question, use vai; otherwise, use tai.
3. Daily diary: Write 3-5 sentences about your day using at least three different conjunctions. This forces you to think about relationships between ideas.
