Reduplication

Reduplication is a word-formation process in which a base, or part of a base, is repeated to produce a new lexeme. In many languages reduplication is fully grammatical, marking plurality, intensity, or aspect; in English it is largely expressive and lexicalised, surviving as a productive but marginal pattern (Bauer 1983; Plag 2003; Mattiello 2013).

Three English Types

English reduplicatives fall into three structural patterns (Marchand 1969; Bauer 1983).

Type	Mechanism	Examples
Exact	Full repetition, no change	bye-bye, choo-choo, no-no, night-night, blah-blah, yada-yada
Ablaut	Repetition with vowel change	flip-flop, tick-tock, ding-dong, chit-chat, mishmash, zigzag, hip-hop, ping-pong, sing-song
Rhyming	Repetition with initial consonant change	hocus-pocus, willy-nilly, hurly-burly, super-duper, hodgepodge, hanky-panky, easy-peasy, okey-dokey, namby-pamby, riff-raff

Ablaut Reduplication and Vowel Order

Ablaut reduplications follow a strikingly consistent vowel order: the first vowel is high or front, the second low or back. The standard sequence is i → a → o: zig-zag, chit-chat, tick-tock, ping-pong, ding-dong, hip-hop. Reverse orders (*zag-zig, *tock-tick) sound wrong to native speakers even though no rule has been explicitly taught. The pattern reflects a phonological tendency in English (and many other languages) for the higher, fronter vowel to come first in expressive doublets.

When all three vowels appear in one item, the order is also fixed: bish-bash-bosh, never *bosh-bash-bish.

Rhyming Reduplication

Rhyming reduplications repeat the rhyme of the base while changing the onset, often substituting an initial /h/, /w/, /p/, or /sh/: hocus-pocus, willy-nilly, hanky-panky, super-duper. Many are semi-fossilised; a small number remain mildly productive in informal coining (easy-peasy, helter-skelter, fuddy-duddy).

Semantic Function

English reduplicatives are concentrated in expressive, evaluative, and child-directed registers. Common semantic effects include:

• Diminution and affection: bye-bye, night-night, choo-choo (often child-directed).
• Imitation: tick-tock, ding-dong, ping-pong (sound-mimetic).
• Triviality or dismissal: yada-yada, blah-blah, hocus-pocus, mumbo-jumbo.
• Disorder or randomness: willy-nilly, helter-skelter, hodgepodge, mishmash.
• Intensification: super-duper, teeny-weeny.

The shared feature is informal register: reduplicatives almost never appear in academic or formal writing.

Reduplication Cross-Linguistically

In many languages reduplication is grammatically central. Indonesian and Malay use reduplication for plurality (orang "person", orang-orang "people"). Tagalog uses partial reduplication for verbal aspect. Mandarin reduplicates verbs to mark tentativeness or brevity (kàn-kàn "have a look"). The English pattern, by contrast, is lexicalised rather than grammatical: each reduplicative is a single fixed item, not a regular morphological operation.

Teaching Implications

Reduplicatives sit at the periphery of ELT vocabulary, but a small set of high-frequency items is worth knowing for listening comprehension and natural-sounding informal speech: flip-flops (footwear), zigzag, ping-pong, hip-hop, super-duper, easy-peasy, blah-blah-blah, hodgepodge. The pedagogical value is twofold. First, reduplicatives are memorable and high-engagement, useful for pronunciation work on vowel contrasts and stress patterns. Second, awareness of the i-before-a-before-o ordering helps learners produce and recognise novel reduplicatives without sounding awkward. The register caveat applies: these items are informal and should not appear in academic writing.
