In the following opinion piece in the Spectator written by a Dutch author he uses single quotation marks to represent or highlight concepts rather than direct speech. Here are three example of him using single quotes:
This ‘stolen country’ paradigm has spread like wildfire
in hopes of solving the ‘native question’.
Many in the US seem to have no clue just how much of a ‘city on a hill’ the US is still perceived to be
it’s the convention in certain disciplines such as philosophy, theology, and linguistics to highlight words with special meaning by using single quotation marks
Can anyone reference an official style guide where this style of quotation marks is accepted? Maybe one written for Dutch writers if its a cultural usage or from a certain discipline like History.
