Miquel Civil (Sabadell, 1926 Chicago, 2019) began writing An outlineof Sumerian grammar in Catalan during his stay in Barcelona, and usedit in the language classes he gave at the University of Barcelona'sInstitut del Pr.xim Orient Antic during the 2002-2003 academic year.Although unfinished, the resulting volume offers many originalcontributions, such as Civil's interpretation of the so-calledconjugation prefixes as an expression of the category of voice, andcomprises an effective summary of the eminent linguist's conception of the Sumerian language.
