Ventureño is a member of the extinct Chumashan languages, a group of Native American languages previously spoken by the Chumash people along the coastal areas of Southern California from as far north as San Luis Obispo to as far south as Malibu.

[5] John Peabody Harrington, who compiled most of the data on Ventureño, used a modified version of the International Phonetic Alphabet.

Harrington differed from the International Phonetic Alphabet in the following symbols: a kappa ⟨к⟩ (small-cap 'k') for [q], a ⟨q⟩ for [x], a slanted bar ⟨ł⟩ for [ɬ], a reversed apostrophe ⟨‘⟩ for aspiration, and a right-turned (standard) apostrophe ⟨’⟩ for a glottal stop (this symbol was also used for ejectives and glottalized sonorants).

[6] The Barbareño/Ventureño Band of Mission Indians has adopted an Americanist form of transcription for Ventureño based on the work done by Harrington: ⟨š⟩ for [ʃ], ⟨ł⟩ for [ɬ], ⟨x⟩ for [x], ⟨ʰ⟩ for aspiration, ⟨y⟩ for [j], and ⟨q⟩ for [q].

This is illustrated in the table below by the nominalized verb meaning "your wanting to make fun of us".
