This article presents data on lexical development of 881 Israeli Hebrew-speaking monolingual toddlers ages 1;0 to 2;0. A Web-based version of the Hebrew MacArthur-Bates Communicative Development Inventories (H-MB-CDI) was used for data collection. Growth curves for expressive vocabulary, receptive vocabulary, actions and gestures were characterized. Developmental trajectories of toddlers with various demographic characteristics, such as education, income, religiosity level, birth order of the child, and child-care arrangements were compared. Results show that the lexical growth curves for Hebrew are comparable to those reported for other languages. Sex, birth order, and child-care arrangements were found to influence the size of lexicons. It is recommended that the trajectories presented here be used as norms for lexical growth among typical Hebrew-speaking toddlers in the second year of life.
