This volume gathers selected papers from the workshops Facing Movement and Meeting Clitics held in the context of the Barcelona Linguistic Institute. The authors explore a wide variety of languages, from Icelandic to Mayan, from Japanese to Russian and Italian, from various data sources: adult grammar, first and second language acquisition, developmental language disorders and language change.The papers on movement address the issues of reconstruction in parasitic gaps; the alternation between short and long distance movement in Germanic; subextraction from subjects; wh- in situ in Greek; word order alternations derived by movement in bilingual acquisition; intervention effects in L2 acquisition of Chinese; multiple wh- fronting in L2; and production of wh- questions in L1, L2 and SLI in French.In the papers on clitics, the theoretical issues considered include: the affixal character of subject clitics in L1; the morphological complexity of clitics; proclisis versus enclisis; the restrictions on cooccurrence of clitics in causative and other constructions; clitic placement in relation to L2 and language change; clitics as demarcative markers; and the acquisition of pronominal clitics in European Portuguese.
