Broca's aphasia is still a relatively poorly understood phenomenon. The Trace Deletion Hypothesis is one of the attempts made to explain linguistically comprehension deficits observable in this disorder. The article presents the main assumptions, claims and consequences of this hypothesis, as well as criticisms it has raised in the literature. This hypothesis offers an opportunity for shedding more light on the issue of agrammatism in Broca's aphasia, and also for improving our understanding of the phenomenon of aphasia as such and, consequently, our understanding of language processing in the human mind.
