Re-duplicatives are one of the many ways new words are made in English. Re-duplicatives are words made by copying the sound of the first word in the second.

Example
'Honky-tonk', 'wishy-washy', 'mish-mash' and 'ping-pong' are examples of re-duplicative words.

In the classroom
Re-duplicatives are an interesting and creative area of vocabulary, and can be exploited to practise problematic areas of pronunciation, such as consonant clusters and rhyming sounds.
