echo ${"Hello World"}
echo $"Hello World"
ShellCheck found a parameter expansion ${...} that contains an unexpected syntax element, such as single or double quotes.
${...}
In the example, this was due to wrapping a translated string $".." with curly braces, which is not valid.
$".."
It is unclear what the intention is with invalid expansions like ${'foo'}, ${$"foo"}, so please look up how to do what you were trying to do.
${'foo'}
${$"foo"}
