'Sit' is intransitive (the subject sits); 'set' is transitive (the subject places something somewhere).
"Sit" does not need an object: the subject sits down on their own. Its past tense is "sat": "She sat down". You are not placing anyone; someone sits.
Please sit down, the presentation will begin in just a few minutes.
She sat at her desk for six hours straight and only got up when the building alarm went off.
He tends to sit at the back of the room during meetings so he can observe the group dynamics.
"Set" needs an object: you place something somewhere. Its past tense is also "set" (irregular): "He set the cup on the table". There is always something you are placing.
Could you set the projector up before the clients arrive? We want everything ready.
She set her phone to silent before entering the theater and forgot to turn the sound back on afterward.
Set the glasses on the table to the right of each plate, the wine glasses go on the outside.
Common mistake
Trick to remember it
Same trick as lay/lie: is there a direct object? Yes = SET (you place something). No = SIT (someone seats themselves). Conjugations: SIT→sat→sat (irregular past). SET→set→set (always the same). "She SAT down" = she seated herself (not "she setted down").
Quick rule
Did you know?
SET is one of the verbs with the most distinct meanings in the English dictionary. The 1989 Oxford English Dictionary devoted over 60,000 words of definition to it with 430 distinct classified uses, making it one of the longest entries in the dictionary's entire history. Among its many meanings: to place, to adjust, to harden (cement "sets"), to go down (the sun "sets"), to be located (the story "is set in Paris"), and as a noun for a related group of things (a set of tools). "The sun sets" is the most famous intransitive exception of the normally transitive verb. And in Southern American dialectal speech, "set" is informally used as a synonym for "sit": "Set down, honey", but in standard modern English they are verbs with different grammatical functions.
