Show the answer

Vowels are described by height, backness and rounding. Plotting the first two against each other gives the vowel quadrilateral. Jones's eight reference points are the cardinal vowels, and RP is analysed with 12 monophthongs.

Why

The last blank catches people out because 20 is the total vowel count including diphthongs. Keeping the two numbers apart matters when comparing accents, since it is almost always the diphthongs that differ.
