The use of locative prepositions by Hebrew-speaking children aged 2; 0-3; o, was investigated in a cross-sectional study. Thirty kibbutz children served as subjects. The spontaneous utterances of each child were analyzed and scored for the frequency with which the child supplied obligatory contexts for locative expressions as well as for appropriate use. The findings suggest the following order of acquisition: be- ' in'; le- 'to'; le+ pronominal suffixes ‘to’ (dative); al 'on'; le ‘to’ (directional); mi-'from'; al-yad 'beside'; meaxorey 'behind'; mitaxat le- ‘under’. The role of formal linguistic complexity in determining that order is discussed. Special reference is made to the contrast between enclitic prefix prepositions and separate word prepositions that express the same locative notions.
