Etc

[Tina]

Everyone uses etc but some [noobs] do not know what it means.

Heres the meaning:
et cetera, a Latin expression meaning and other things or and so on

[Sonia]

Etc is an abbreviation for Et Cetera, a Latin saying that means and other things, but people commonly use it when they cant think of anything else to put on a list, but know they are other things that can go on that list. During the example I am stating, between these: *, an [asterisk], means that he/she is thinking, not speaking.

[Raeanne Dimick]

Etc., with a period included, means and so on.

The period serves no purpose, and it is commonly dropped, particularly in places such as Twitter, where space is at a premium. The requirement for a period at the end in order to be proper needs to be dropped.
