I understand that there is no universal rule regarding the use of single or double quotation marks or use of italics, however I wasn't sure whether scare quotes need to follow same format one has ascribed to. Could I use different inverted commas to differentiate scare quotes?
If I’m consistent, would it be acceptable to use the following style in a British PhD thesis (interdisciplinary approach).
Italics: foreign words, first appearance of specialist terms, discussion/emphasis of a specific word/term, titles of books and papers.
Single inverted commas: literary quotes, extracts from interviews.
Double inverted commas: scare quotes, quotes within quotes.
My reasoning for this was that I wanted to make a clear distinction between my regular use of inverted commas (direct quotes), italics (terms being discussed) and scare quotes (terms questionable usage).
