What is the infinitive (dictionary) form of tarkistan?

The dictionary form is tarkistaa. This is a Type II Finnish verb (ends in -aa/-ää in the infinitive). When conjugated for “I,” -a/-ä becomes -n, giving tarkistan.

---

Why is the subject minä omitted in this sentence?

Finnish is a pro-drop language: the verb ending -n already tells you the subject is “I.” You can add Minä for emphasis or clarity, but it’s normally dropped.

Example with pronoun:
Minä tarkistan postilaatikkoni joka aamu.

What is postilaatikkoni, and what case is it in?

Postilaatikkoni breaks down into postilaatikko (mailbox) + the possessive suffix -ni (my). It functions as the direct object here in the nominative (or “object”) form.

Key points:

• It’s a whole (complete) object, so Finnish uses the nominative/accusative rather than partitive.
• The same form works for both subject and complete object when there’s a possessive suffix.

---

How does the possessive suffix -ni work in postilaatikkoni?

The suffix -ni marks first person singular possession: “my.” When you attach -ni to postilaatikko, you get postilaatikkoni = “my mailbox.” You can optionally reinforce it with minun (my):

• Minun postilaatikkoni = “my mailbox” (more emphatic/redundant)
• Postilaatikkoni = “my mailbox” (standard)

---

Why isn’t postilaatikkoni in the partitive case (e.g. postilaatikkoani)?

In Finnish, you use the partitive case to indicate incomplete or ongoing actions, or “some of” something. Here you check the entire mailbox (a complete, finished action), so you use the non-partitive form (nominative/accusative). Using the partitive (postilaatikkoani) would imply you’re only checking part of it, or that the action is incomplete.

What does joka aamu mean, and how is it formed?

Joka aamu means “every morning.” It’s made from:

• joka = every
• aamu = morning (nominative)

Together they form a temporal adverbial expressing a habitual time: every single morning.

---

Can joka aamu be moved around in the sentence?

Yes. Finnish word order is fairly flexible with adverbials. All of these mean essentially the same:

• Tarkistan postilaatikkoni joka aamu.
• Joka aamu tarkistan postilaatikkoni.
• Tarkistan joka aamu postilaatikkoni.

Moving joka aamu can shift emphasis but doesn’t change the core meaning.

---

Could I use tarkastaa instead of tarkistaa?

Yes. Tarkastaa also means “to check/inspect.” Many speakers say Tarkastan postilaatikkoni joka aamu with no big difference in everyday use. Subtle nuance:

• tarkistaa often implies a quick check or verification
• tarkastaa can feel a bit more thorough or formal, like an inspection or audit

---

How can I make “every morning” stronger or more emphatic?

You can say:

• joka ikinen aamu = every single morning
• aina joka aamu = always every morning
• tasan joka aamu = exactly every morning (if you want to stress punctuality)
