Ben okuldan sonra parkta yürüyorum.

Yes, you can usually leave ben out.

Turkish verbs already show the subject, and yürüyorum means I am walking / I walk, so the -um ending already tells you it is I.

So both of these are natural:

• Ben okuldan sonra parkta yürüyorum.
• Okuldan sonra parkta yürüyorum.

Using ben adds emphasis, like:

• I walk in the park after school.

It literally means after school.

Breakdown:

• okul = school
• -dan = from
• sonra = after

So okuldan sonra is literally after/from school, which is the normal Turkish way to say after school.

This same pattern is very common:

• işten sonra = after work
• yemekten sonra = after the meal / after eating
• dersten sonra = after class

Because in Turkish, sonra usually goes with the ablative case: -dan / -den / -tan / -ten.

So when you say after X, Turkish normally says X + ablative + sonra.

Examples:

• okuldan sonra = after school
• dersten sonra = after class
• toplantıdan sonra = after the meeting

So okul sonra would sound incomplete or incorrect in standard Turkish.

Parkta means in the park / at the park, not to the park.

Breakdown:

• park = park
• -ta = in / at

So:

• parkta yürüyorum = I am walking in the park

If you wanted to the park, you would use the dative ending:

• parka gidiyorum = I am going to the park

This is an important contrast:

• parkta = in/at the park
• parka = to the park

Yürüyorum means I am walking and often also I walk, depending on context.

Breakdown:

• yürü- = walk
• -yor- = present continuous marker
• -um = I

So:

• yürüyorum = I am walking

This same pattern appears in many verbs:

• gidiyorum = I am going
• okuyorum = I am reading
• yazıyorum = I am writing

It can mean both, depending on context.

Turkish -yor often covers both:

• an action happening now
• a regular or habitual action

So Ben okuldan sonra parkta yürüyorum can mean:

• I am walking in the park after school
• I walk in the park after school

If the sentence is describing a routine, English often uses the simple present (I walk), but Turkish commonly still uses -yor.

The sentence is:

• Ben = I
• okuldan sonra = after school
• parkta = in the park
• yürüyorum = I am walking

So the order is:

Subject + time expression + place + verb

This is very natural in Turkish.

A key difference from English is that the verb often comes at the end.

So instead of:

• I walk in the park after school

Turkish naturally says something like:

• I after school in the park walk

That does not mean Turkish word order is completely fixed, but verb-final order is very common.

Yes, Turkish word order is flexible, but some versions sound more neutral than others.

The most neutral version here is:

• Ben okuldan sonra parkta yürüyorum.

You could also say:

• Okuldan sonra parkta yürüyorum.
• Parkta okuldan sonra yürüyorum.
• Yürüyorum okuldan sonra parkta.
  This is much less neutral and would sound marked or poetic/conversational in a special context.

Turkish changes word order mainly for emphasis or focus, not because the grammar changes completely.

Turkish does not have articles like a/an and the.

So:

• okul can mean school or the school, depending on context
• park can mean park or the park, depending on context

In this sentence, English might translate it as:

• after school
• in the park

But Turkish does not need separate article words.

This is because of a sound rule in Turkish.

The locative ending is written as one of these forms:

• -da
• -de
• -ta
• -te

After certain voiceless consonants like p, ç, t, k, f, h, s, ş, the ending usually becomes -ta / -te instead of -da / -de.

Since park ends in k, you get:

• parkta

not

• parkda

The same kind of thing happens with the ablative:

• okuldan
• but parktan

They are different cases with different meanings.

• -dan / -den / -tan / -ten = from
• -da / -de / -ta / -te = in / at

So:

• okuldan sonra = after school
  literally from school after
• parkta = in the park

They also change form because of vowel harmony and consonant rules.

For example:

• evde = at home
• okulda = at school
• parkta = in the park
• işten sonra = after work

Usually it just means after school in general.

Even though -dan literally has a from meaning, in this expression the whole phrase works like the English time expression after school.

So in normal usage, it usually refers to the time period after school ends, not necessarily the physical act of walking out of the building.

You add the negative marker -mA- before -yor.

So:

• Ben okuldan sonra parkta yürümüyorum.

This means:

• I am not walking in the park after school or
• I do not walk in the park after school

Breakdown:

• yürü- = walk
• -mü- = negative
• -yor = present continuous
• -um = I

You add the question particle mu / mü / mı / mi separately.

So:

• Ben okuldan sonra parkta yürüyor muyum?

This means:

• Am I walking in the park after school? or
• Do I walk in the park after school?

In everyday speech, you would more naturally ask someone else something like:

• Okuldan sonra parkta yürüyor musun? = Do you walk / Are you walking in the park after school?

A rough pronunciation guide is:

• Ben → like ben
• okuldan → oh-kool-dan
• sonra → son-rah
• parkta → park-tah
• yürüyorum → roughly yuh-roo-yor-oom

A few useful notes:

• ü is not an English u sound; it is more like the vowel in German ü or French u
• Turkish letters are pronounced quite consistently
• stress often falls naturally near the end of phrases, but Turkish stress patterns can vary

Yes, but it means something a little different.

• yürüyorum = I am walking / I walk
• yürürüm = I walk / I usually walk / I will walk in some contexts

Yürürüm is more like the aorist, often used for habits, general truths, or willingness.

So:

• Okuldan sonra parkta yürüyorum = I walk / I’m walking in the park after school
• Okuldan sonra parkta yürürüm = I usually walk in the park after school

For many everyday routine statements, learners will often hear -yor forms more often than they expect.
