Questions & Answers about Minä lisään maitoa teehen.

Why is the word for milk, maitoa, in the partitive case?

Because it refers to an indefinite, unbounded amount of a mass noun. With verbs like lisätä (to add), when you add “some” of a substance, Finnish typically uses the partitive singular (here: maitoa). It signals that you’re not talking about a whole, clearly delimited object but an unspecified quantity.

Could I say maidon instead of maitoa?

Yes, but the meaning changes. Maidon (genitive/“total object”) is used when the addition is treated as a complete, delimited amount—often specific or measured:

• Lisään maidon teehen. = I add the (measured/specified) milk to the tea.
  This could be a recipe step after you’ve measured “the milk.”
  In everyday talk about adding “some milk,” maitoa is more natural.

What does the ending -n on lisään mean?

It marks 1st person singular present indicative: “I.” The verb is lisätä (type 4). Present forms:

• minä lisään
• sinä lisäät
• hän lisää
• me lisäämme
• te lisäätte
• he lisäävät

Do I need the pronoun Minä?

No. The person is already shown by the verb ending.

• Neutral: Lisään maitoa teehen.
• With emphasis/contrast: Minä lisään maitoa teehen (as opposed to someone else).

What case is teehen, and why does it mean “into the tea”?

Teehen is the illative case, which expresses movement “into” something. The noun tee ends in a long vowel, so the illative uses the -hVn pattern: tee → teehen (“into tea”).

Why not teen or teeseen?

• Teen is the genitive of tee (“of tea”) and also happens to be “I do” from tehdä—so not the right form for “into.”
• You may also encounter teeseen as an illative variant in modern usage. Style guides typically list teehen as the primary, safest choice. If you want to be sure, use teehen.

How is tee commonly declined in useful cases?

• Nominative: tee (tea)
• Genitive: teen (of tea)
• Partitive: teetä (some tea)
• Inessive: teessä (in tea)
• Elative: teestä (out of/from tea)
• Illative: teehen (into tea; also seen as teeseen)

Could I say teessä with lisätä if I mean “in the tea”?

With lisätä, you normally use the illative (movement into): teehen.
Use teessä to state location: Maito on teessä = The milk is in the tea.
But for the act of adding, say Lisään maitoa teehen.

Is there any preposition for “to” here?

No. Finnish uses case endings instead of prepositions. The “to/into” meaning is carried by the illative ending: teehen.

What’s the difference between lisätä, laittaa, and kaataa here?

• lisätä = to add (a neutral/recipe-like choice: adding an ingredient to a mixture).
• laittaa = to put (very common, broad meaning; also fine: Laitan maitoa teehen).
• kaataa = to pour (focus on the pouring action: Kaadan maitoa teehen).

Can the word order change?

Yes. Finnish word order is flexible for emphasis:

• Neutral: (Minä) lisään maitoa teehen.
• Emphasize destination: Teehen lisään maitoa.
• Emphasize what is being added: Maitoakin lisään teehen (even milk I add to tea).
  The default S–V–O–(adverbials) order is the most common in neutral contexts.

How do I make this negative?

Use the negative verb plus the basic stem of the main verb:

• En lisää maitoa teehen. = I don’t add milk to tea.
  Note it’s lisää, not lisään, after the negative verb en.

How do I ask “Do you add milk to tea?” and answer briefly?

• Question (2nd person, -ko/-kö): Lisäätkö maitoa teehen?
• Short answers: Lisään. / En lisää.

How do I say “into my tea”?

Use a possessive suffix (more formal/standard) or a possessive pronoun:

• Lisään maitoa teeheni. (into my tea)
• Also acceptable: Lisään maitoa minun teeheni.
  Colloquially many speakers say minun teehen (without the suffix), but teeheni is the textbook-safe form.

How is maitoa formed from maito?

It’s the partitive singular. For maito (a back-vowel word), the partitive adds -a: maito → maitoa.
Other useful forms:

• Genitive: maidon
• Illative: maitoon
• Inessive: maidossa

Does the present tense lisään also cover future meaning?

Yes. Finnish has no separate future tense. Lisään maitoa teehen can mean “I add” or “I will add,” depending on context.

How should I pronounce the long vowels and h here?

• lisään: long ää (sustain the vowel).
• teehen: long ee, and the h is pronounced; don’t say just teen.
• maitoa: three syllables: ma–i–toa.

How would I express a general preference like “I take my tea with milk”?

Use the adessive “with” construction:

• Juon teetä maidolla. = I drink tea with milk.
