A lisp (OE wlisp, stammering)1 is a speech impediment, historically also known as sigmatism.2 Stereotypically, people with a lisp are unable to pronounce sibilants (like the sound [s]), and replace them with interdentals (like the sound [θ]), though there are actually several kinds of lisp. The result is that the speech is unclear.
- "Interdental" lisping is produced when the tip of the tongue protrudes between the front teeth and "dentalised" lisping is produced when the tip of the tongue just touches the front teeth.
- The "lateral" lisp, where the /s/ and /z/ sounds are produced with air escaping over the sides of the tongue, is also called 'slushy ess' or a 'slushy lisp' due to the wet, spitty sound. The symbols for these lateralized sounds are in the Extended International Phonetic Alphabet for speech disorders, [ʪ] and [ʫ]. Notably the former mayor of New York, Rudolph Giuliani, has this type of lisp.3
- Finally, there is the "palatal lisp," where the speaker attempts to make the sounds with the tongue in contact with the palate.2
