“Here – let me adjust the seat for you.”
You're going on a bike ride with a friend. She doesn't have a bicycle, so you let her borrow yours. You're taller than she is, so the seat is too high for her. You offer to lower the seat for her.
Here – let me adjust the seat for you.
This is a polite way to offer to help someone:
Here - let me hold the door for you.
Here - let me make a copy of that for you.
It's common for people to say "here" when offering to help or take responsibility:
"Adjusting" something means making small changes to it to make it better.
Some other good examples of "adjusting" something are:
- You can "adjust the temperature" in a room on the thermostat.
- Comparisons of money between the past and present are often "adjusted for inflation". That means that the older amounts are multiplied by the amount that the value of money has risen by over time. So $400 in 1980 might be equal to $900 today, for example.
- Before you start driving, you're supposed to adjust the mirrors on your car so that you can see behind the car easily.
- You adjust the settings of a machine, a computer program, or an appliance.
What's the difference between a "seat" and a "chair"? A chair is one specific kind of seat. The chair sitting at your desk is a "chair" and a "seat". However, a bench is also a "seat" but is not a "chair".
We usually use the word "seat", not "chair", for seats in cars, on planes, bicycles, trains, motorcycles, and so on.
