Learn about Access reserved words and symbols
"Reserved words" are words and symbols that have a specific meaning to Microsoft Access. If you use a reserved word or symbol to name a field in a desktop database or web app table, Access warns you that the word is reserved and that you might encounter errors when referring to the field.
You might also encounter errors if you use a reserved word to name a control, an object, or a variable. The error messages you receive don't necessarily tell you that a reserved word is the cause of the problem. As a result, it can be difficult to identify what needs to be changed. For example, Access might display a message similar to the following:
The wizard was unable to preview your report, possibly because a table needed by your report is exclusively locked.
If a reserved word is already in use, you can avoid error messages by surrounding each occurrence of the word with brackets ([ ]). However, the best solution is to change the name to a nonreserved word.
Note: It is not practical to provide a list of all reserved words, such as built-in function names or user-defined names. If you set a reference to a type library, an object library, or an ActiveX control, that library's reserved words are also reserved words in your database.

Access reserved symbols
The following symbols must not be used as part of a field name or as part of an object name:
| . / * ; : ! # & - ? " ' $ % |
Access database engine reserved words
The Access database engine runs in different modes, depending on whether it is called from Access, data access objects, the Microsoft OLE Provider for the Access database engine, or the Microsoft Access ODBC driver. It can be run in either ANSI mode or non-ANSI (traditional) mode.
Because using these two modes results in two slightly different sets of reserved words, a query that uses a reserved word might work in one mode and fail in another mode.
The following is a list of reserved words to avoid when choosing identifier names.
