Bu fikir bana mantıklı geliyor.

Word by word:

• Bu = this
• fikir = idea
• bana = to me
• mantıklı = logical, reasonable, sensible
• geliyor = literally is coming, but here it means seems or feels

So the whole sentence is literally something like:

• This idea comes logical to me

But in natural English, it means:

• This idea seems logical to me
• This idea sounds reasonable to me

Because Turkish uses the dative case here.

• ben = I
• bana = to me

The expression birine ... gelmek often means to seem ... to someone.

So:

• bana mantıklı geliyor = it seems logical to me

You cannot use ben here, because ben is the subject form, and this sentence needs to me, not I.

This is one of the irregular forms of Turkish personal pronouns.

Some important ones are:

• ben → bana = to me
• sen → sana = to you
• o → ona = to him/her/it
• biz → bize = to us
• siz → size = to you
• onlar → onlara = to them

So bana is just the correct dative form of ben. It is very common, and it is best to memorize it as a fixed form.

Great question. In Turkish, gelmek does not only mean physical movement.

In some expressions, it can mean:

• to seem
• to feel
• to strike someone as

So:

• mantıklı geliyor = seems logical
• garip geliyor = seems strange
• iyi geliyor = feels good / does good
• zor geliyor = feels difficult

In this sentence, geliyor is not about something literally coming. It is part of a very common pattern:

• X bana Y geliyor = X seems Y to me

Turkish often uses the -iyor form where English would use a simple present.

So although geliyor literally looks like is coming, here it works very naturally as:

• seems
• feels

This is just the normal way to say it in Turkish.

So:

• Bu fikir bana mantıklı geliyor = This idea seems logical to me

Even though English uses seems, Turkish prefers the -iyor form here.

Mantıklı means:

• logical
• reasonable
• sensible

It comes from:

• mantık = logic
• -lı = a suffix meaning with, having, or characterized by

So mantıklı literally means something like:

• with logic
• logical

You can use it for ideas, plans, explanations, decisions, and so on.

Examples:

• Mantıklı bir cevap = a logical answer
• Mantıklı değil = it is not logical / it does not make sense

Yes, you can.

• Bu fikir mantıklı = This idea is logical / reasonable
• Bu fikir bana mantıklı geliyor = This idea seems logical to me

The difference is small but important:

• Bu fikir mantıklı sounds more direct, like a statement of fact.
• Bu fikir bana mantıklı geliyor sounds more personal and subjective: in my opinion, to me, it seems logical.

So if you want to soften your statement or show that it is your impression, bana ... geliyor is very natural.

No, Turkish word order is flexible.

The neutral order here is:

• Bu fikir bana mantıklı geliyor

But you could also say:

• Bana bu fikir mantıklı geliyor
• Bu fikir mantıklı geliyor bana
  This is possible in speech, though less neutral.

The meaning stays basically the same, but the emphasis changes.

For example:

• Bana bu fikir mantıklı geliyor emphasizes to me
• Bu fikir bana mantıklı geliyor is the most balanced, natural version

The subject is Bu fikir = this idea.

So the sentence structure is roughly:

• Bu fikir = subject
• bana = to me
• mantıklı = logical
• geliyor = seems

In other words:

• This idea seems logical to me

Yes, if the meaning is clear or if you do not want to say to me explicitly.

For example:

• Bu fikir mantıklı geliyor = This idea seems logical

This is still natural.

But when you say:

• Bu fikir bana mantıklı geliyor

you make it clear that this is your personal impression.

It is neutral and very natural in both speech and writing.

It is not slang, and it is not especially formal either. You can use it in:

• everyday conversation
• work discussions
• class
• writing
• polite disagreement

For example, it is a useful phrase when giving an opinion without sounding too strong.

Geliyor is pronounced roughly like:

• ge-li-yor

The ğ in Turkish usually does not sound like a strong consonant. In geliyor, it mainly softens or lengthens the sound a little rather than being clearly pronounced like an English g.

So learners often hear it almost like:

• geliyor
• or very slightly stretched between vowels

The important thing is not to pronounce it as a hard English g.

Yes, in many contexts that is a very good natural translation.

Depending on context, Bu fikir bana mantıklı geliyor can mean:

• This idea seems logical to me
• This idea sounds reasonable to me
• This idea makes sense to me

The exact English choice depends on tone and context, but all three can work.

Many adjectives work in this pattern. For example:

• Bu fikir bana ilginç geliyor = This idea seems interesting to me
• Bu fikir bana garip geliyor = This idea seems strange to me
• Bu fikir bana doğru geliyor = This idea seems right to me
• Bu fikir bana saçma geliyor = This idea seems absurd / silly to me
• Bu fikir bana zor geliyor = This idea seems difficult to me

So the pattern is very useful:

• X bana Y geliyor = X seems Y to me
