In this project, we will challenge the claim that iconicity cannot be used to refer to abstract concepts by looking at sign languages, the manual-visual languages of deaf communities. Sign languages excel from spoken languages because their lexicons include a large number of iconic signs. The high prevalence of iconicity in sign languages does not deter their capacity to express abstract concepts and in fact iconicity is typically used to refer to both concrete and abstract concepts. For example, in German Sign Language (DGS) the iconic sign TO-WRITE depicts a person writing with a pen. Interestingly, the same sign also represents the abstract concept SCHOOL. This is not the case in British Sign Language (BSL) where the sign SCHOOL has a completely arbitrary form. In this project, Prof. Pamela Perniss (University of Cologne) and Dr. Gerardo Ortega (English Language and Linguistics, UoB) will compare the form and meaning of the lexicons of two unrelated sign languages (DGS and BSL) and determine how iconicity or arbitrariness interact with different semantic domains to refer to concrete and abstract concepts.
