We'll begin when everyone arrives.

[Alice Chu]

Please tell me the difference between the two sentences below.
Is the first sentence used more often?


1. We'll begin when everyone arrives.

2. We'll begin when everyone has arrived.

Why don't you tell us what you think the difference might be, Alice?

And in what context you want to use them. Give us an actual situation to consider.

1. The meeting will begin when everyone arrives. Let’s wait patiently.
It means everyone will arrive and then the meeting will begin.
“Arrives” means an action in the future.

2. The meeting will begin when everyone has arrived. Let’s wait patiently.
It means everyone will have arrived before the meeting begins.
“Has arrived” refers to a completed action in the future.

I would use the first sentence below instead of the second one.

1. I will buy a new car when I save enough money.
2. I will buy a new car when I have saved enough money.

You need to get away from these very strict rules of tense usage that you seem to obsess over. For the majority of native speakers, these two sentences mean the same:

The meeting will start when everyone arrives.
The meeting will start when everyone has arrived.

 

[5jj]

You need to get away from these very strict rules of tense usage that you seem to obsess over.

As you have been told on several occasions, Alice.

Tenses and aspects help to give clear meaning only in full context.
