Он намекнул, что встречу лучше перенести на завтра.

Because it is the direct object of перенести.

• Dictionary form: встреча = meeting
• Accusative singular: встречу

In перенести встречу, the meeting is the thing being moved/rescheduled, so it takes the accusative.

A useful pattern:

• перенести урок = move/reschedule the lesson
• перенести поездку = move/reschedule the trip
• перенести встречу = move/reschedule the meeting

Намекнул is perfective past tense. It presents the hint as a single completed act: he hinted.

• намекнул = he gave a hint / he hinted once
• намекал = he was hinting / he kept hinting / he used to hint

In this sentence, the speaker refers to one finished action, so намекнул is natural.

Here лучше means it would be better or better to.

So:

• встречу лучше перенести на завтра = it would be better to move the meeting to tomorrow

Russian often uses лучше with an infinitive in a very compact way:

• Лучше подождать. = It’s better to wait.
• Лучше уйти сейчас. = It’s better to leave now.

There is no need for a separate word like it.

Russian often leaves that idea unstated. English usually needs something like it would be better to..., but Russian can simply say:

• лучше перенести = better to move / it would be better to move

If you want, Russian can make this more explicit in some contexts:

• лучше было бы перенести... = it would be better to move...

But in everyday speech, the shorter version is very common.

Because it follows лучше in a structure meaning better to do something.

Pattern:

• лучше + infinitive

Examples:

• Лучше остаться дома. = Better to stay home.
• Лучше обсудить это позже. = Better to discuss it later.
• Лучше перенести встречу. = Better to reschedule the meeting.

So перенести stays in the infinitive because it expresses the action that is being recommended.

Because the sentence refers to a single complete action: moving/rescheduling the meeting once.

• переносить (imperfective) = to be moving, to move repeatedly, to be in the process of rescheduling
• перенести (perfective) = to move/reschedule once, as a completed action

Here the idea is not be rescheduling, but reschedule it. That is why перенести fits.

Literally, на завтра is something like for tomorrow.

With actions like postponing, moving, rescheduling, Russian often uses:

• перенести на понедельник = move to Monday
• перенести на вечер = move to the evening
• перенести на завтра = move to tomorrow

So на marks the new scheduled time.

This is different from simply saying завтра = tomorrow in a general time sense.

Not naturally with перенести in this meaning.

• перенести на завтра = reschedule for tomorrow

If you just say перенести завтра, it would sound like move it tomorrow — meaning the action of moving happens tomorrow, not that the meeting is rescheduled for tomorrow.

So на завтра is important because it shows the new date/time of the meeting.

Because что introduces a subordinate clause.

Main clause:

• Он намекнул = He hinted

Subordinate clause:

• что встречу лучше перенести на завтра = that it would be better to move the meeting to tomorrow

Russian normally separates these with a comma:

• Он намекнул, что...

This is very standard punctuation.

In this sentence, yes: что means that and introduces what he hinted.

But что is a very common Russian word and can mean different things in different contexts, such as:

• what
• that

Here it is definitely the conjunction that:

• Он намекнул, что... = He hinted that...

Russian often leaves the subject of an infinitive unstated when it is obvious from context.

Here:

• встречу лучше перенести на завтра = it would be better to move the meeting to tomorrow

The sentence does not explicitly say who should do it. Depending on context, it could mean:

• we should move it
• they should move it
• someone should move it

Russian is often less explicit than English about this.

Он means he and is the subject of намекнул.

• Он намекнул = He hinted

Russian can sometimes omit subject pronouns when they are understood from context, but here он is useful because it clearly identifies who did the hinting.

Without it, намекнул, что... could still be possible in context, but it would sound more dependent on previous sentences.

Yes. Russian word order is flexible, though different orders shift emphasis.

Standard neutral order:

• Он намекнул, что встречу лучше перенести на завтра.

Other possible orders:

• Он намекнул, что лучше перенести встречу на завтра.
• Он намекнул, что на завтра лучше перенести встречу.

These all mean roughly the same thing, but the emphasis changes slightly:

• встречу earlier can foreground the meeting
• на завтра earlier can foreground the new date
• лучше перенести earlier can foreground the recommendation

The version you have is completely natural.

It is weaker and less direct.

• сказал = said directly
• намекнул = hinted, suggested indirectly

So this sentence implies that he did not openly say Let’s move the meeting to tomorrow, but gave an indirect sign or suggestion.

That nuance is important:

• Он сказал, что... = He said that...
• Он намекнул, что... = He hinted that...

Yes, in conversational Russian it can.

It would mean:

• The meeting should probably be moved to tomorrow
• It would be better to move the meeting to tomorrow

Russian often allows this kind of subjectless recommendation. The full sentence simply places it inside the clause after что:

• Он намекнул, что...

It is neutral and natural in both spoken and written Russian.

None of the words are especially slangy or highly formal:

• намекнул = neutral
• встречу = neutral
• лучше перенести = neutral
• на завтра = neutral

So it works well in everyday conversation, business contexts, and general writing.
