Linke tıklayıp onay kutusunu işaretledim, sonra da senin esprine güldüm.

Tıklayıp comes from tıklamak = to click.

It is formed like this:

• tıkla- = click
• -yıp / -ip = a linking suffix that means something like and, after, or by doing

So linke tıklayıp onay kutusunu işaretledim literally feels like:

• clicking on the link, I checked the checkbox
• or more natural English: I clicked on the link and checked the checkbox

This -(y)ıp / -(y)ip / -(y)up / -(y)üp form is very common in Turkish for linking actions done by the same subject.

Because tıklamak usually takes the dative case in Turkish:

• bir şeye tıklamak = to click on something

So:

• link = link
• linke = to/on the link

A native English speaker often expects a direct object here, because English says click the link. But Turkish commonly structures it more like click on the link.

You may sometimes hear linki tıklamak too, especially in modern tech usage, but linke tıklamak is a very normal and standard pattern.

This is a great question because Turkish noun phrases often stack endings.

Onay kutusu is a compound noun:

• onay = approval / confirmation
• kutu = box
• onay kutusu = checkbox / confirmation box

The -su here is part of the compound structure. It does not literally mean his/her box in this sentence; it is just how many Turkish noun compounds are formed.

Then the whole noun becomes the definite direct object of işaretledim:

• onay kutusunu işaretledim = I checked/marked the checkbox

So the final breakdown is:

• onay kutu-su = checkbox
• onay kutusu-nu = the checkbox, as a definite object

That extra -n- is a buffer consonant before the accusative ending.

İşaretledim comes from işaretlemek = to mark, indicate, tick, check.

Breakdown:

• işaretle- = mark / check
• -di- = past tense
• -m = I

So:

• işaretledim = I marked / I checked

In the context of a checkbox, it naturally means I checked or I ticked.

Sonra means afterward / then / later.

The separate word da here means also / too / and. In this sentence, it helps continue the sequence:

• sonra da = and then / then also

So the sentence flows like:

• I clicked the link and checked the checkbox, and then I laughed at your joke.

Important: this da is written separately, because it is the particle meaning also/too, not the case ending -de / -da.

Because gülmek takes the dative case, not a direct object.

In Turkish:

• birine gülmek = to laugh at someone
• bir şeye gülmek = to laugh at something

So:

• esprine güldüm = I laughed at your joke

The form esprine is built like this:

• espri = joke
• esprin = your joke
• esprine = to/at your joke

English uses laugh at, and Turkish also treats it as something like laugh to/at with the dative, not as a direct object.

Because Turkish often allows both:

• the possessor pronoun: senin = your
• and the possessive suffix on the noun: esprin / esprine = your joke / to your joke

So senin esprine literally has both markers of possession, but that is normal Turkish.

Compare:

• esprine güldüm = I laughed at your joke
• senin esprine güldüm = I laughed at your joke

The second version can add a little more clarity, emphasis, or contrast. It is not wrong or redundant in an unnatural way; it is a standard Turkish pattern.

Turkish usually does not need a separate subject pronoun if the verb ending already shows the subject.

Here, both verbs tell you the subject is I:

• işaretledim = I checked
• güldüm = I laughed

The -m at the end marks first person singular.

So Turkish often says the equivalent of:

• Checked the box, then laughed at your joke

but the verb endings already make it clear that the subject is I.

Because of vowel harmony.

Both are past tense + first person singular, but the vowel changes to match the vowel pattern of the stem.

• işaretledim = işaretle- + -di + -m
• güldüm = gül- + -dü + -m

The past suffix is basically -DI, where the vowel changes:

• -dı
• -di
• -du
• -dü

And the first-person ending is -m.

So the meaning is the same kind of ending in both verbs; only the vowel changes to fit Turkish sound harmony.

The sentence has two linked parts:

1. Linke tıklayıp onay kutusunu işaretledim

   • I clicked on the link and checked the checkbox

2. sonra da senin esprine güldüm

   • and then I laughed at your joke

A few key structure points:

• Turkish often puts the verb at the end of a clause.
• The -ıp form links two actions with the same subject.
• The subject I is omitted because the verb endings already show it.
• Turkish uses case endings where English often uses prepositions or direct objects.

So the sentence is very natural Turkish narrative sequencing:
did X, did Y, then did Z.
