Question

1. there: used in speech after a noun to emphasize which person, thing, etc., you are referring to

2. there: used in speech after a noun to emphasize which person, thing, etc. you are referring to
================================
Q1: Do we have to use "etc.," or "etc." in the sentence?
Q2: In Webster Dictionary, 'there' is classified as an adjective. However, in Webster Learner's Dictionary, 'there' is classified as an adverb. It is strange. How come it is classified differently? For example in the following: Ask that man there. That clock there once belonged to my great-grandmother.

Answer 1

1. ~~> ... etc., you are ...

2. In both of those examples, you are reading forms of colloquial speech. Remember that English, like Japanese, Korean, German, etc., are living languages, and changes occur over time. Sometimes those changes are results of dialects and/or very casual use. Sometimes those changes are results of new ideas and things in our world. Consider how the word "chip" has changed and been added to over the past few decades.

Answer 2

Thank you for your help.
Do you mean both are correct?

1. there: used in speech after a noun to emphasize which person, thing, etc., you are referring to

2. there: used in speech after a noun to emphasize which person, thing, etc. you are referring to

It seems that in a dictionary, 'etc.,' is used, and in another dictionary, 'etc.' is used. Why do we need to use "," after 'etc.'?
