Hän luki kirjan viime vuonna.

Finnish does not normally mark gender in third-person singular pronouns. Hän can mean either he or she, depending on context.

So in this sentence, hän could refer to a man or a woman. You only know which one from the wider context.

A useful comparison:

• hän = he / she
• he = they

This often surprises English speakers because English requires a gender choice in the singular, but Finnish does not.

Luki is the past tense form of the verb lukea (to read).

In this sentence, luki means read in the sense of read something / was in the past and completed in context.

Basic breakdown:

• dictionary form: lukea = to read
• past stem: luki-
• 3rd person singular past: luki = he/she read

This is the imperfect tense in Finnish, which is the normal simple past tense.

Because kirjan is the object form used here, not the basic dictionary form.

• kirja = book (basic form, nominative)
• kirjan = object form here

In this sentence, kirjan shows that the book was read as a whole / completely. In Finnish, the object often changes form depending on whether the action is seen as complete or incomplete.

So:

• Hän luki kirjan. = He/She read the whole book.
• Hän luki kirjaa. = He/She was reading a book / some of the book.

This is one of the most important object patterns in Finnish.

This is a very common learner question, because the form looks like the genitive singular.

In a sentence like this, kirjan is usually explained as the total object. Traditionally, some grammars call this an accusative function, but the form itself is the same as the genitive singular.

So in practice:

• form: kirjan
• function here: total object = the reading was completed

For learners, the most useful thing is not the label, but the meaning: kirjan tells you the object is affected in a complete/resultative way.

That would change the meaning.

• Hän luki kirjan viime vuonna. = He/She read the book, meaning the whole book was completed last year.
• Hän luki kirjaa viime vuonna. = He/She was reading a book last year, or was engaged in reading it, without focusing on completion.

So the contrast is roughly:

• kirjan = completed object
• kirjaa = partial/incomplete/ongoing object

English often leaves this kind of distinction vague, but Finnish often makes it visible in the object case.

Viime vuonna means last year.

Breakdown:

• viime = last / previous
• vuonna = a case form of vuosi (year)

The form vuonna is the essive case, which is often used in time expressions. In expressions like this, it can feel a bit like in the year.

So literally, viime vuonna is something like:

• during the previous year
• or loosely in the last year

But the natural English translation is simply last year.

Because Finnish often uses special case forms in time expressions.

• vuosi = year (basic form)
• vuonna = in the year / during the year in this kind of expression

You see the same pattern in other examples:

• ensi vuonna = next year
• tänä vuonna = this year
• viime vuonna = last year

So this is not random: Finnish is using a case ending to express time.

Finnish has no articles like English a or the.

That means Finnish does not have separate words corresponding directly to English a/an and the. Whether something is a book or the book is understood from context.

So kirjan could be understood as:

• a book
• the book

In this sentence, English would often translate it as the book because the whole object is completed and the context may make it specific, but Finnish itself does not use an article.

Yes, you could. Finnish word order is more flexible than English word order.

The sentence:

• Hän luki kirjan viime vuonna.

is a neutral, natural order.

But these are also possible:

• Viime vuonna hän luki kirjan.
• Kirjan hän luki viime vuonna.

The meaning stays broadly the same, but the emphasis changes:

• Viime vuonna... emphasizes the time
• Kirjan... emphasizes the object

Finnish uses word order partly for information structure and emphasis, not just grammar.

By itself, luki is the simple past form and can sometimes be translated in different ways depending on context. But in this sentence, because the object is kirjan (total object), the natural meaning is read the book, with completion implied.

So here it is best understood as:

• He/She read the book last year

If the sentence had kirjaa instead, it would more naturally suggest:

• He/She was reading a book last year
• or He/She read a book / some of a book last year without focusing on completion

Finnish does not have English-style progressive forms like was reading as a basic tense contrast. Instead, meaning is often shown through context and object case.

These vowels are often difficult for English speakers.

In hän:

• ä is a front vowel, somewhat like the vowel in British cat for some speakers, but it is not exactly the same in all accents.

In luki and kirjan, the vowels are more familiar to English speakers.

In viime vuonna:

• y does not appear there, but learners often ask about Finnish front vowels generally. This sentence uses ä, not y.

A rough pronunciation guide for the whole sentence is:

• hæn lu-ki kir-yan vii-me vuon-na

A few important pronunciation points:

• Finnish letters are pronounced quite consistently.
• Double vowels are long.
• Double consonants are also long.
• Stress usually falls on the first syllable: HÄN luki KIRjan VIIme VUONna.

Because Finnish does not distinguish gender in the pronoun, and the verb also does not change for gender.

English:

• he read
• she read

Finnish:

• hän luki for both

The verb agrees with person and number, not with gender. So the same verb form works for either he or she.

Sometimes yes, but here learners should think of hän as the normal written form.

Finnish can omit pronouns in some contexts, especially when the subject is obvious. But with third person singular, the pronoun is often kept because the verb form alone does not identify the subject very clearly.

So:

• Hän luki kirjan viime vuonna. = fully clear and normal
• Luki kirjan viime vuonna. = possible only in a context where the subject is already obvious, but not the best standalone sentence for a learner

So for standard, clear Finnish, keeping hän is the safest choice.

The structure is:

• Hän = subject
• luki = verb
• kirjan = object
• viime vuonna = time expression

So it follows a very familiar pattern:

Subject + Verb + Object + Time

That is one reason this sentence is a good beginner example: the grammar is Finnish, but the overall structure is easy for an English speaker to recognize.
