Hoş bulduk, davet için teşekkürler.

You use hoş bulduk as the standard reply to hoş geldin or hoş geldiniz.

It is said when someone welcomes you after you arrive somewhere, such as:

• a home
• an office
• a party
• a meeting
• an event

So it is not a general greeting like hello. It specifically answers a welcome.

This is one of the most common learner questions. Grammatically, bulduk looks like we found, but hoş bulduk is a fixed expression. Even if only one person is speaking, Turkish normally uses hoş bulduk.

So the best way to learn it is as a set phrase, not as something you freely rebuild every time.

Word by word:

• hoş = pleasant, nice
• bulduk = we found

So the literal idea is something like we found it pleasant/nice.

But in real life, do not translate it too literally. It functions as the conventional response to being welcomed.

Davet means invitation, and için means for or because of.

Together, davet için means for the invitation.

This is a very common Turkish structure:

• yardım için = for the help
• bilgi için = for the information
• davet için = for the invitation

Here için is a postposition, so it comes after the noun.

Turkish often leaves possession implicit when it is already clear from the situation.

So davet için teşekkürler naturally means thanks for the invitation, even without explicitly saying your.

If you want to make it explicit, you can say:

• davetin için teşekkürler = thanks for your invitation, informal singular
• davetiniz için teşekkürler = thanks for your invitation, formal or plural

The version in your sentence is casual and natural.

Teşekkürler is like thanks, while teşekkür ederim is more like thank you.

So:

• teşekkürler = shorter, more conversational
• teşekkür ederim = fuller, a bit more formal or deliberate

Both are correct. In this sentence, teşekkürler sounds friendly and natural.

It is best described as neutral-polite.

• Hoş bulduk works in both informal and formal situations.
• Teşekkürler makes the second half a little more conversational.

A more formal version could be:

• Hoş bulduk, davetiniz için teşekkür ederim.
• Hoş bulduk, davetiniz için teşekkür ederiz.

The second one is especially natural if you are speaking on behalf of a group.

You can absolutely say the whole sentence together.

• Hoş bulduk answers the welcome.
• Davet için teşekkürler adds gratitude.

So the full sentence is very natural when someone welcomes you to a place and you also want to thank them for inviting you.

The comma separates two short, independent polite expressions:

• Hoş bulduk
• Davet için teşekkürler

In speech, this is just a pause. The comma helps show that pause in writing. It is natural punctuation here.

The sentence as written is already natural, but Turkish can make the second part more explicit if needed.

Examples:

• Hoş bulduk, davetiniz için teşekkür ederim. = singular speaker, more formal
• Hoş bulduk, davetiniz için teşekkür ederiz. = group speaker, or polite institutional tone
• Hoş bulduk, davetin için teşekkürler. = informal, speaking to one person you know well

So the original sentence is a compact, everyday version.
