These phenomena occur in many of these dialects, such as those in most of England and Wales, parts of the United States, and all of the Anglophone societies of the southern hemisphere, with the exception of South Africa.
Linking R and intrusive R may also occur between a root morpheme and certain suffixes, such as -ing or -al. For instance, in words such as draw(r)ing, withdraw(r)al, or Kafka(r)esque.
[8] In many non-rhotic accents, words historically ending in /r/ (as evidenced by an ⟨r⟩ in the spelling) may be pronounced with /r/ when they are closely followed by another morpheme beginning with a vowel sound.
[16] Other recognizable examples are the Beatles singing: "I saw-r-a film today, oh boy" in the song "A Day in the Life", from their 1967 album Sgt.
Varieties that feature linking R but not intrusive R (that is, tuna oil is pronounced [ˈtjuːnə (ʔ)ɔɪl]), show a clear phonemic distinction between words with and without /r/ in the syllable coda.
[20] A 2006 study at the University of Bergen examined the pronunciation of 30 British newsreaders on nationally broadcast newscasts around the turn of the 21st century speaking what was judged to be "mainstream RP".
Factors disfavouring the use of R-sandhi included adjacency to proper names; occurrence immediately before a stressed syllable; the presence of another /r/ in the vicinity; and more formal style (prepared script rather than interview).
