Question

Which group contains centering diphthongs?

• A. /ei/, /ai/, /ɒi/
• B. /әu/, /au/
• C. /iə/, /eə/, /uə/
• D. /a:, æ, ɔː/

Answer 1

Answer:

C. /iə/, /eə/, /uə/

Centering diphthongs end in /ə/ — a central vowel — hence the name. These include sounds like /iə/ (as in "ear") and /eə/ (as in "care").
