In many spoken languages, partial exclamatives exhibit a wh-element occupying the same position it occupies in wh-interrogative sentences.
In LIS, a manual wh-morpheme has not been identified, as the different wh-signs do not share a common value for any formational parameter. What identifies wh-signs as a natural class is their grammatical function, their distribution in the clause and a specific non-manual marker, that is, furrowed eyebrows. Partial exclamative sentences in LIS are produced with furrowed eyebrows, as shown in the examples below.
