Japanese often expresses ideas like bring by combining verbs.
The て-form of 持つ is 持って, which links it to 来る.
So the structure is:
This is normal Japanese, not an unusual construction.
の turns the verb phrase into something noun-like, and は marks it as the topic.
So:
In this sentence, it sets up the question:
This pattern is very common for asking who did X?
Yes, but the nuance matters.
Because of だっけ, the speaker is not usually asking for brand-new information. They are trying to remember something they were told before.
So a more natural sense is:
The again here is the English memory-refreshing again, not repetition of the action.
だっけ is an informal expression used when trying to recall something.
It often gives a feeling like:
So:
It sounds casual and conversational.
They are quite different in nuance.
だれ？ = Who?
だれだっけ？ = Who was it again?
So in this sentence, だっけ shows that the speaker is searching their memory, not simply asking from zero.
Yes, だっけ is casual.
A more polite version would be something like:
That sounds more polite and appropriate in formal situations.
Very casual:
More polite:
Both have the trying to remember nuance.
Because the sentence uses the pattern:
This structure means:
So だれ comes after のは as the thing being identified.
Compare:
This is a very natural pattern in Japanese. You do not need が before だれ here.
Because the bringing already happened.
The speaker is asking about a completed action in the past:
The だっけ part is about the speaker’s memory now, but the action itself is past.
The spaces are almost certainly just for learners.
Normal Japanese is usually written without spaces:
The spaces in your sentence are there to make the grammar easier to see:
They are not normally written that way in standard Japanese text.
Here, の is not the possession particle like in 私の本.
Instead, it is a nominalizer. It turns a clause into something noun-like.
So:
In this sentence, it helps create the structure:
So this の is grammatical, not possessive.
Yes, ペグ is a loanword from English peg. In camping context, it usually means tent pegs or stakes.
So テント と ペグ naturally means something like:
The camping context makes that interpretation clear.
