# Reserved Words

Keywords in Ocient® are specific words that the database can interpret either as SQL syntax or unquoted identifiers. You cannot use a subset of them, named reserved words, as unquoted identifiers without introducing parsing ambiguities in the database. As a result, when you use these words as an identifier, you must surround the reserved word with double quotes.

You can find these words in the `sys.reserved_words` system catalog table.
