Mitrovic and Sauerland (2014, 2016) claim that across languages DP-conjunction decomposes into [XP1 MU] [J [XP2 MU]]]. Languages vary wrt. which of the J or MU-particles are pronounced. Our study focuses on Georgian, a language that shows triadic exponence of J and MU. The aim of this work is to test Mitrovic and Sauerland’s (2014, 2016) account by investing the comprehension of conjunctive expressions by Georgian-speaking chidren (28 children; 3;9-5;10, M = 4;9). Our results show that (i) J-MU expressions are more difficult to comprehend than J expressions, (ii) J-MU expressions are more difficult to comprehend than MU expressions. Our results constitute a challenge
for the account by Mitrovic and Sauerland (2014, 2016) and other existing accounts of conjunctive expressions (Brasoveanu and Szabolcsi 2013, Szabolcsi 2015, a.o.).
