|English vocabulary- sit at or on the computer|
What is the difference between sitting at, sitting in, or sitting on the computer?
Generally, it is more appropriate to say "sit at a computer" rather than "sit on a computer". This is because "at" indicates a location where you are using the computer, while "on" suggests that you are physically sitting on top of the computer.
However, there may be some situations where "sit on a computer" could be used metaphorically or in a creative way. For example, if someone was using a large computer tower as a seat, they might say "I'm sitting on my computer" as a playful or humorous statement.
In most cases though, it's better to use "sit at a computer" to indicate that you are working or using the computer as intended.
