Agrammatic aphasia is characterized by non-fluent speech in which free and bound grammatical morphemes are frequently omitted or substituted.However, not all grammatical morphemes are equally vulnerable.The present paper focuses on grammatical morphemes that are used for time reference.For this, some languages used verb morphology, others use grammatical tone or free morphemes, so-called 'aspectual adverbs' .Data from nine different languages will be presented and it will be shown that reference to the past is selectively impaired in agrammatic speakers of languages that use verb inflections for time reference.However, in languages that use aspectual adverbs, this selective deficit does not occur.These results will be discussed in relation to the linguistic concept of Discourse Linking.
