The abbreviation etc. is taken from Latin “Et cetera” which means “And other things.”
It is the equivalent of Indonesian “Dan lain-lain”.
It appears at the end of the list when there is no point to give any more example.
Etc. cannot be used in formal writings.
Some rules to keep in mind when we are using it:
1. It is incorrect to write “… And etc.” since ‘et’ means ‘And’.
2. There should be at least 2 items in a sentence when you want to use etc.
Correct example: “We need you to bring cookies, candies, etc. to the party.”
Incorrect example: “I would like to buy books, etc. at the corner shop.”
3. Etc. is not to be used for people. For people, there is “et al.”
Et al. is from the Latin “et alii” which means “And other people.”
Example: “We went to the party with Nobita, Shizuka, Giant, et al.”
4. You cannot use etc. when you already use “such as”, “like”, “for example”.
Why? Because it means you want to give a complete example of all the things you want to say.
Correct example: “She bought new cooking utensils such as knives, plates, forks, and spoons.”
Correct example: “She bought knives, plates, etc. for her new kitchen.”
In American English, etc. is written with a period (tanda titik), even in midsentence.
Example: “Cats, dogs, rats, etc. are all different kinds of animal living in the house.”
