Marul ve turpu yıkayıp salataya dereotu ekledim.

It is the verb yıkamak (to wash) with the converb suffix -(y)Ip: yıka- + yıp = yıkayıp.

This form links two actions done by the same subject. So:

• yıkayıp ... ekledim = I washed ... and added ...
• It can also feel like having washed ..., I added ...

The tense and person are not inside yıkayıp. They come from the main verb ekledim.

The sentence splits like this:

• Marul ve turpu yıkayıp = washing the lettuce and the radish
• salataya dereotu ekledim = I added dill to the salad

So:

• marul ve turpu goes with yıkayıp
• salataya dereotu goes with ekledim

That is a very common Turkish pattern: first action in -(y)Ip, then the main action at the end.

The -u is the accusative suffix -(y)I, which is often used for a specific direct object.

Because turp ends in a consonant, Turkish adds the suffix directly:

• turp + u = turpu

And because of vowel harmony, the suffix vowel is u here.

So turpu is the accusative form of turp.

When nouns are joined by ve (and), Turkish often puts the case ending only on the last noun, and that ending can apply to the whole coordinated phrase.

So marul ve turpu can function as one accusative object meaning:

• the lettuce and the radish

You could also say marulu ve turpu. That is possible too, but marking only the last item is very normal.

This is the dative case -(y)A, which often means to, into, or toward.

Because salata ends in a vowel, Turkish inserts a buffer y:

• salata + ya = salataya

So salataya means to/into the salad.

Because here it is a bare direct object, not an accusative-marked one.

In Turkish, a bare object often means something non-specific or generic. So dereotu ekledim is like:

• I added dill
• I added some dill

If you meant a specific dill already known from context, dereotunu ekledim would be possible.

It breaks down like this:

• ekle- = add
• -di = past tense
• -m = first person singular (I)

So ekledim means I added.

Because Turkish often leaves subject pronouns out when the verb already shows the person.

In ekledim, the ending -m already tells you the subject is I. So ben is not necessary.

You would usually add ben only for emphasis or contrast.

Turkish normally prefers verb-final word order.

A neutral order is often:

• subject
• objects / other sentence elements
• verb

In this sentence, the final verb ekledim carries the main tense and person information, so it naturally comes at the end.

Usually yes.

The -(y)Ip form often connects actions in sequence, especially when the sentence sounds like an instruction or recipe step. So here the natural reading is:

• first wash
• then add

It also strongly suggests that the same person did both actions.

In Turkish, nouns are often left in the singular when they refer to ingredients, substances, or items whose exact number is not important.

So marul, turp, and dereotu do not need plural endings here. Turkish usually adds the plural only when the sentence really needs to emphasize more than one.
