The purpose of this study was to determine the natural order of acquisition of the proform it, comparing deictic pronoun it, anaphoric pronoun it and expletive it. Files from four children (Adam, Eve, Nina and Peter) aged 1 ; 6–3 ; 0 in the CHILDES database were coded for occurrences of NP it (here it is) and expletive it (it's raining). Occurrences of NP it were coded for whether they followed an overt discourse anaphor (anaphoric it) or not (deictic it). All children examined produce deictic and anaphoric pronoun it from the very first files, but do not produce expletive it until 2–7 months later. Following Inoue's (1991) lexical-semantic reanalysis account of the acquisition of expletive there after locative there, we propose that children acquire expletive it by reanalyzing referential pronoun it to include an expletive subtype. This reanalysis takes place when children realize that expletive it never co-occurs with any deictic/anaphoric referent.

Results of a study are presented that suggest the grammatical structures of English some deaf and hard of hearing students struggle to acquire. A review of the literature from the past 40 years is presented, exploring particular lexical and morphosyntactic areas in which deaf and hard of hearing children have traditionally exhibited difficulty. Twenty-six participants from an urban day school for the deaf used the LanguageLinks software, produced by Laureate Learning Systems, for 10 minutes daily for 9 weeks. The descriptive analysis of the results expands on findings reported by Cannon, Easterbrooks, Gagne, and Beal-Alvarez (2011). The results indicated that many participants struggled with regular noun singular/plural; accusative first- and second-person singular; noun/verb agreement copular "be"; accusative third-person number/ gender; locative pronominals; auxiliary "be"/regular past "-ed;" and prenominal determiners plural.

This is the first part of a two-part article that reviews a number of the current debates regarding raising and control constructions. The issues addressed in this part include the syntactic attributes governing their distribution; the characterization of the relevant silent elements; the empirical properties which may distinguish/unify the two classes of constructions (on either syntactic or semantic grounds).
