Viime aikoina olen ollut todella väsynyt töiden jälkeen.

In Finnish, the subject pronoun is often left out when the verb already shows who the subject is.

Here, olen means I am or, in this structure, I have. The ending -n tells you it is first person singular: I.

So:

• (minä) olen = I am / I have
• minä is optional here

You could say Minä olen ollut todella väsynyt töiden jälkeen, but it usually sounds more natural without minä unless you want emphasis, contrast, or clarity.

Olen ollut is the present perfect form, roughly I have been.

This fits well with viime aikoina (lately / recently), because the sentence is talking about a situation that has been true during a recent period up to now.

Compare:

• olen väsynyt = I am tired
  -> my current state right now
• olin väsynyt = I was tired
  -> a finished past situation
• olen ollut väsynyt = I have been tired
  -> true repeatedly or continuously in the recent past, with relevance to now

So Viime aikoina olen ollut... is a very natural combination.

It is made with:

• the present tense of olla (to be) -> olen
• plus the past participle ollut

So:

• olen ollut = have been

This is how Finnish forms the perfect tense:

• olen tehnyt = I have done
• olen nähnyt = I have seen
• olen ollut = I have been

In this sentence, ollut is part of the tense, while väsynyt describes the state.

Viime aikoina means lately / recently / in recent times.

Literally, it is something like during the latest times. Finnish uses the plural here in a way that sounds completely natural, even though English would usually not say recent times in everyday conversation.

A learner-friendly way to handle it is to treat viime aikoina as a fixed expression meaning:

• lately
• recently
• these days

The form aikoina is an old established case form used in this expression. You do not need to build it from scratch every time at the beginner stage; it is best learned as a chunk: viime aikoina.

Väsynyt means tired. In this sentence, it works like an adjective describing the subject.

So the structure is:

• olen ollut = have been
• todella väsynyt = really tired

Even though väsynyt historically comes from a participle, in normal learner terms it is best understood here simply as an adjective meaning tired.

Similar examples:

• olen iloinen = I am happy
• olen ollut kiireinen = I have been busy
• olen ollut väsynyt = I have been tired

Yes, todella here means really or very, strengthening väsynyt.

So:

• väsynyt = tired
• todella väsynyt = really tired / very tired

A few common intensifiers in Finnish are:

• todella = really, very
• tosi = really, very, quite informal
• hyvin = very

All of these can work in many contexts, but todella sounds natural and neutral here.

For example:

• todella väsynyt = neutral, natural
• tosi väsynyt = a bit more conversational
• hyvin väsynyt = also possible, though sometimes a bit more formal or literal depending on context

Jälkeen means after, and it is a postposition.

That means it comes after the word it relates to, unlike English after, which comes before:

• English: after work
• Finnish: work after -> töiden jälkeen

A very important grammar point is that jälkeen requires the word before it to be in the genitive form.

So:

• töiden = genitive form
• jälkeen = after

Together:

• töiden jälkeen = after work

This same pattern appears in other expressions too:

• ruoan jälkeen = after food / after the meal
• koulun jälkeen = after school
• sen jälkeen = after that

This is a very common learner question. In Finnish, töiden jälkeen is the normal idiomatic way to say after work in the sense of after the workday / after finishing work.

Here töiden is the genitive plural of työ (work).

Why plural? Because Finnish often conceptualizes work as the day’s work tasks or duties, where English uses the mass noun work.

So:

• töiden jälkeen = after work, after the workday
• työn jälkeen = after the work / after a piece of work / after the job

Both are possible in some contexts, but töiden jälkeen is especially common when talking about everyday life:

• Olen usein väsynyt töiden jälkeen. = I’m often tired after work.

You may also see the alternative spelling/form töitten jälkeen, which means the same thing.

Finnish word order is fairly flexible, but the original order is very natural.

Viime aikoina olen ollut todella väsynyt töiden jälkeen works well because it starts with the time expression viime aikoina (lately), setting the scene first.

Other orders are possible, for example:

• Olen viime aikoina ollut todella väsynyt töiden jälkeen.
• Töiden jälkeen olen viime aikoina ollut todella väsynyt.

These are grammatically possible, but they may shift the emphasis a little.

In neutral everyday Finnish, the original sentence is a very good model:

• Viime aikoina = time frame first
• olen ollut = verb
• todella väsynyt = description
• töiden jälkeen = after-work context

So the word order is not completely fixed, but this version is natural and idiomatic.
