Illegal Column Names?

[Mark Vancura]

I found myself trying to create a table with a column named "Usage" which documents how the object of this row is used, but I get:
create table junk (Usage varchar(8192)) ;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'usage varchar(8192))' at line 1

Is there a way to escape the name so that I can still use it?
Is there a list of illegal names so that I know which ones to escape?

This works:
create table junk(wsage varchar(8192)) ;
Query OK, 0 rows affected (0.22 sec)

So it is only "usage" in all case variations, that is illegal.

I need a work-around.
