Speaking with a speech impediment where 's' sounds are pronounced like 'th,' or speaking softly and in a whispering way.
From Old English 'wlispian' or related Germanic roots. The 'w' dropped off over centuries. The onomatopoetic quality of the word itself mimics the soft 'th' sound of a lisp.
Lisps are so common in young children that they're part of normal speech development—kids usually outgrow them by age 6-7, but many famous people kept slight lisps into adulthood as a distinctive speech pattern.
Historically coded as feminine or queer deviance; pathologized in speech therapy (mostly affecting children, esp. girls). Used pejoratively to mock gay men and women. Combines disability stigma with gender/sexuality bias.
Use 'speech variation' or specific phonetic term. Avoid 'lisping' in casual mockery. Frame as natural variation, not defect.
["interdental fricative variation","speech variation","rhotacism (or specific phonetic descriptor)"]
Many lisp naturally (interdental /s/); others adopt it socially. Destigmatize as variation, not failure. Recognize speech therapy's history of enforcing gender/sexuality norms.
