Others, for example author and translator Hillel Halkin, oppose Zuckermann's model. In an article published on 24 December 2004 in The Jewish Daily Forward, pseudonymous column "Philologos", Halkin accused Zuckermann of political agenda. Zuckermann's response was published on 28 December 2004 in "The Mendele Review: Yiddish Literature and Language". As described by Reuters in a 2006 article, "Zuckermann's lectures are packed, with the cream of Israeli academia invariably looking uncertain on whether to endorse his innovative streak or rise to the defense of the mother tongue." According to Omri Herzog ("Haaretz"), Zuckermann "is considered by his Israeli colleagues either a genius or a provocateur". "In 2011 [...] Zuckermann contacted the Barngarla community about helping to revive and reclaim the Barngarla language. This request was eagerly accepted by the Barngarla people and language reclamation workshops began in Port Lincoln, Whyalla and Port Augusta in 2012" (Barngarla man Stephen Atkinson, 2013). The reclamation is based on 170-year-old documents. Zuckermann is the founder and convener of the Adelaide Language Festival. Zuckermann's research focuses on contact linguistics, lexicology, revivalistics, Jewish languages, and the study of language, culture and identity. Zuckermann argues that Israeli Hebrew, which he calls "Israeli", is a hybrid language that is genetically both Indo-European (Germanic, Slavic and Romance) and Afro-Asiatic (Semitic). He suggests that "Israeli" is the continuation not only of literary Hebrew(s) but also of Yiddish, as well as Polish, Russian, German, English, Ladino, Arabic and other languages spoken by Hebrew revivalists. Zuckermann's hybridic synthesis is in contrast to both the traditional revival thesis (i.e. that "Israeli" is Hebrew revived) and the relexification antithesis (i.e. that "Israeli" is Yiddish with Hebrew words). While his synthesis is multi-parental, both the thesis and the antithesis are mono-parental. Zuckermann introduces revivalistics as a new transdisciplinary field of enquiry surrounding language reclamation (e.g. Barngarla), revitalization (e.g. Adnyamathanha) and reinvigoration (e.g. Irish). Complementing documentary linguistics, revivalistics aims to provide a systematic analysis especially of attempts to resurrect no-longer spoken languages (reclamation) but also of initiatives to reverse language shift (revitalization and reinvigoration).
