How do I tell powershell the end of a variable to be expanded into a string when it sits next to other alphabetic characters?
$StringToAdd = "iss"
$CompeteString = "Miss$StringToAddippi"
Thanks!

You can create a variable by simply assigning it a value. For example, the command $var4 = “variableexample” creates a variable named $var4 and assigns it a string value. The double quotes (” “) indicate that a string value is being assigned to the variable.
The Clear-Variable cmdlet deletes the data stored in a variable, but it does not delete the variable. As a result, the value of the variable is NULL (empty). If the variable has a specified data or object type, this cmdlet preserves the type of the object stored in the variable.
So, you can use $ExecutionContext. InvokeCommand. ExpandString("$Domain\$User") and voila! You've expanded your string.
Using PowerShell, you can interpolate a literal string containing one or more placeholders. The output of that command replaces the placeholder with the value it contains. Many programming languages make use of string interpolation or variable interpolation.
Use curly braces, { and }, to delimit the variable expansion. For example:
PS C:\> $StringToAdd = "iss"
PS C:\> $CompeteString = "Miss${StringToAdd}ippi"
PS C:\> $CompeteString
Mississippi
You can use $()
PS C:\> $StringToAdd = "iss"
PS C:\> $CompeteString = "Miss$($StringToAdd)ippi"
PS C:\> $CompeteString
Mississippi
The sub-expression operator for double-quoted strings is described here. Whatever is in the brackets should be evaluated first. This can be a variable or even an expression.
PS C:\> $CompeteString = "Miss$($StringToAdd.length * 2)ippi"
PS C:\> $CompeteString
Miss6ippi
