“…Both within and across sign languages, nouns can be derived from verbs through a variety of methods, including changing mouthing ( Johnston, 2001 ), combining multiple signs ( Tkachman & Sandler, 2013 ), and changing the morphophonological structure of the verb, including modifying the handshape or movement of the sign ( Abner, 2017 , Kimmelman, Klezovich, & Moroz, 2018 ; Padden et al, 2015 ). Reduplication of the verb is a robust form of noun derivation in sign languages ( Abner, 2017 ; Supalla & Newport, 1978 ). Accompanying the reduplication of a signed verb is a change in the quality of sign movement such that the movement of the noun is smaller and more restrained relative to the verb, leading to a shorter articulation time ( Hunger, 2006 ).…”
