Rica ederim, her zaman.

Yes. Even though you can analyze its parts, Rica ederim is best learned as a set phrase used as a polite response to thanks.

A word-for-word breakdown does not help very much here, because the whole expression functions idiomatically. In real use, learners should treat it as one standard reply.

• rica is a noun meaning something like request or favor
• ederim comes from etmek, a very common verb meaning to do / to make

So structurally, this is a noun + etmek expression, which is very common in Turkish. Other examples are:

• yardım etmek = to help
• telefon etmek = to phone
• teklif etmek = to offer / propose

In Rica ederim, the important thing is not the literal breakdown, but the fact that it has become a standard polite formula.

Because ederim is the aorist / simple present form, and Turkish often uses that form in polite formulas.

So:

• ederim = a general, habitual, formula-like I do
• ediyorum = I am doing

In this expression, Rica ediyorum would sound wrong or unnatural for the usual reply to thanks.
The fixed phrase is Rica ederim.

This is similar to other formal or polite expressions in Turkish where the aorist sounds more natural than the progressive.

Because Turkish verbs already show the subject.

In ederim, the ending -im tells you the subject is I. So ben is not needed.

• ederim = I do / I say
• ben rica ederim would usually sound unnecessary unless you are emphasizing I

Turkish often leaves out subject pronouns when the verb already makes the person clear.

It is neutral and polite. That means it is safe in almost any situation:

• with strangers
• at work
• with teachers
• in shops
• in everyday polite conversation

It does not sound overly stiff, but it is a little more polished than some casual alternatives. So for learners, it is one of the safest replies to use.

Her zaman literally means always or every time.

In this sentence, it adds the feeling of:

• any time
• always
• you’re welcome anytime

So Rica ederim is already complete on its own, and her zaman just makes the reply warmer or more emphatic.

Because it is made from two separate words:

• her = every
• zaman = time

Together they form an adverbial phrase meaning always or any time, but Turkish writes them separately.

So:

• her zaman = correct
• herzaman = incorrect in standard Turkish

It is understandable and natural enough, but in many everyday situations people would simply say:

• Rica ederim

That is the most standard reply.

Adding her zaman is possible if you want to sound extra warm, like any time. In conversation, the first part does most of the work, and the second part is an extra friendly touch.

Not really. The comma just shows a small pause in writing.

You may see:

• Rica ederim, her zaman.
• Rica ederim. Her zaman.
• just Rica ederim.

In speech, this is mainly about rhythm and emphasis, not a major grammar point.

A rough English-friendly pronunciation is:

ree-JAH eh-deh-REEM, hehr zah-MAHN

A few useful pronunciation notes:

• Turkish c is pronounced like English j in jam
  • so rica sounds like ri-ja
• the r is usually lightly tapped
• stress is often near the end of the word:
  • riCA
  • edeRİM
  • zaMAN

You do not need to make it sound dramatic; a smooth, even pronunciation works well.

Sometimes, yes, especially if the context already makes the meaning clear. It can feel like anytime in English.

However, for a learner, Rica ederim is the safer and more standard standalone reply.
So if you are unsure, use:

• Rica ederim

and treat her zaman as an optional extra.

Yes. A few common ones are:

• Bir şey değil = it’s nothing
• Ne demek = don’t mention it
• Önemli değil = it’s not important
• Her zaman = anytime

These differ a little in tone, but Rica ederim is one of the safest and most universally appropriate choices for learners.
