itsy-bitsy

Dialects, like all varieties of English, use a number of reduplicated forms. Many of these are associated with baby talk, and the compound itsy-bitsy could have been popularized by the nursery rhyme 'Itsy-bitsy spider'. Other rhyming phrases associated with smallness are teeny-weeny and teensy-weensy. Dialect terms for 'little' include dinky, titchy, and totty.
