Notes
1According to CitationDryer (2008), in 16% of the languages of the world polar questions lack interrogative lexico-syntax, in 40% there is no polar question particle.
2The mixture of syntactic and phonological terminology in this label is unfortunate.
3Although according to CitationSchegloff (2007, p. 26) one may occasionally find minimal two-turn sequences here.
4In Kendon's understanding, an F-formation arises “when two or more people cooperate together to maintain a space between them to which they all have direct and exclusive access” (1990, p. 210).
