Noun and verb comprehension and production was investigated in two groups of late bilingual, Greek–English speakers: individuals with anomic aphasia and a control group of non-brain injured individuals matched for age and gender. There were no signiWcant diVerences in verb or noun comprehension between the two groups in either language. However, verb and noun production during picture naming was signiWcantly worse in the bilingual individuals with anomic aphasia in both languages, who also showed a speciWc verb impairment in Greek and English. The potential underlying level of breakdown of the speciWc verb impairment was further investigation with reference to two speciWc features of verbs: instrumentality and verb–noun relationship. Additional results revealed a facilitatory eVect of Instrumentality in both languages. However, there was no eVect of verb–noun name relation in Greek, and a negative eVect of verb–noun name relation was observed in English. Lemma retrieval seemed to be intact in this group of bilingual individuals whose main problem seemed to arise during the retrieval of the phonological representation of the target word. This impairment was greater in English. The Wndings are discussed in terms of three current models of word production.
