About Reserved Words
Lists the reserved words that cannot be used as identifiers because they have a special meaning in PowerShell.
There are certain words that have special meaning in PowerShell. When these words appear without quotation marks, PowerShell attempts to apply their special meaning rather than treating them as character strings. To use these words as parameter arguments in a command or script without invoking their special meaning, enclose the reserved words in quotation marks.
The following are the reserved words in PowerShell:
assembly exit process base filter public begin finally return break for sequence catch foreach static class from (*) switch command function throw configuration hidden trap continue if try data in type define (*) inlinescript until do interface using dynamicparam module var (*) else namespace while elseif parallel workflow end param enum private (*) These keywords are reserved for future use.
