@learnativenglish: Fee fie fo fum! I smell ablaut duplication. Ablaut reduplication is the natural linguistic phenomenon of a repeated phrase where the vowels move from front-to-back or high-to-low in the mouth, almost always following the vowel sequence I – A – O. Badda bing, badda bang, badda boom. Saying words in reverse sounds unnatural or wrong to native speakers (e.g., tick-tock sounds right, while tock-tick does not). Can you think of any other examples? Share them in the comments! . . . . . . Thank you to Adastra Speech for the marked IPA vowel sound chart. #learnEnglish #peonunciation #ablautreduplication #phonetics #internationalphoneticalphabet
