Ablaut combinations

The reduplicative compounds resemble in sound form the rhyme combinations like razzle-dazzle and ablaut combinations like sing-song. These two types, therefore, are treated by many¹ as repetition with change of initial consonant or with vowel interchange. H. Marchand treats these as pseudo-compounds, which occur as twin forms with phonic variation and as twin forms with a rhyme for characteristic feature.

Ablaut combinations are twin forms consisting of one basic morpheme (usually the second), sometimes a pseudo-morpheme which is repeated in the other constituent with a different vowel. The typical changes are [ı]— [æ]: chit-chat ‘gossip’ (from chat ‘easy familiar talk’), dilly-dally ‘loiter’, knick-knack ‘small articles of ornament’, riff-raff ‘the mob’, shilly-shally ‘hesitate’, zigzag (borrowed from French), and [ı] — [o]: ding-dong (said of the sound of a bell), ping-pong ‘table-tennis’, singsong ‘monotonous voice’, tiptop ‘first-rate’. The free forms corresponding to the basic morphemes are as a rule expressive words denoting sound or movement.

Both groups are based on sound symbolism expressing polarity. With words denoting movement these words symbolise to and fro rhythm: criss-cross; the to and fro movement also suggests hesitation: shilly-shally (probably based on the question “Shall I?"); alternating noises: pitter-patter. The semantically predominant group are the words meaning idle talk: bibble-babble, chit-chat, clitter-clatter, etc.
