Editing Expressive aphasia (section)

===Overlap with receptive aphasia===
In addition to difficulty expressing oneself, individuals with expressive aphasia are also noted to commonly have trouble with comprehension in certain linguistic areas. This agrammatism overlaps with receptive aphasia, but can be seen in patients who have expressive aphasia without being diagnosed as having receptive aphasia. The most well-noted of these are object-relative clauses, object Wh- questions, and topicalized structures (placing the topic at the beginning of the sentence).<ref name="Friedmann">{{cite book | last1 = Friedmann | first1 = Naama | last2 = Gvion | first2 = Aviah | last3 = Novogrodsky | first3 = Rama | chapter = Syntactic Movement in Agrammatism and S-SLI: Two Different Impairments | editor = Adriana Belletti | title = Language Acquisition and Development: Proceedings of GALA2005 | publisher = Cambridge Scholars Press | year = 2006 | location = Newcastle, UK | pages = 197–210 | url = http://www.language-brain.com/docs/Friedmann_Gvion_Novogrodsky_movementSLI_agrammatism.pdf | access-date = 2024-02-21 | archive-url = https://web.archive.org/web/20141211030552/http://www.language-brain.com/docs/Friedmann_Gvion_Novogrodsky_movementSLI_agrammatism.pdf | archive-date = 2014-12-11 | url-status = dead | isbn = 9781847180285 |oclc=133524617 | display-editors = etal}}</ref> These three concepts all share phrasal movement, which can cause words to lose their thematic roles when they change order in the sentence.<ref name="Friedmann" /> This is often not an issue for people without agrammatic aphasias, but many people with aphasia rely heavily on word order to understand roles that words play within the sentence.<ref>{{Cite journal |last1=Bates |first1=Elizabeth A. |last2=Friederici |first2=Angela D. |last3=Wulfeck |first3=Beverly B. |last4=Juarez |first4=Larry A. |date=1988-03-01 |title=On the preservation of word order in aphasia: Cross-linguistic evidence |url=https://dx.doi.org/10.1016/0093-934X%2888%2990072-7 |journal=Brain and Language |language=en |volume=33 |issue=2 |pages=323–364 |doi=10.1016/0093-934X(88)90072-7 |pmid=3359173 |s2cid=23236428 |issn=0093-934X}}</ref>
