Linguistic theory helps in the understanding of how and why language operates in the manner it does. It provides insight into ways we can improve communication strategies to achieve deeply rooted communicative expectations. This is particularly important in the clinical context, where patients and their families rely heavily on the information exchange they have with health professionals (HPs). Linguistic theory also makes evident the strong link between communication and basic ethical principles that lie at the core of medicine, and which provide justification for the requirement of informed consent and other decision-making models such as shared decision-making. In their paper "Treatability Statements in Serious Illness: The Gap Between What is Said and What is Heard," Batten and colleagues take seriously the miscommunication that can occur between patients and their families, and health professionals (HPs); attempt to justify this with reference to linguistic theory; and consider the implications of such miscommunication on shared decision-making and informed consent, both of which are intricately related to and informed by ethical theory. We view Batten and colleagues' paper as a significant contribution to the limited literature in this area because it draws attention to the inherent communication deficiencies in the most serious of contexts: communication with patients and their families about life and death matters. While our interpretations differ from the authors', we welcome the opportunity to advance this important discussion in the hope that we will provide further insight into how and why such miscommunication may come about. 1 Batten and colleagues focus on what they call "treatability statements," and, more specifically, on miscommunication that may arise from the HPs' use of words such as 'treat', its derivatives, or synonymous phrases in discussions with patients suffering life-limiting conditions such as terminal cancer. They contend that some HPs' (specifically oncologists') use of the word 'treat' in treatability statements is "technical" and that, in using it, HPs do not intend to convey any information about the curability or amelioration of the patients' condition. Physicians assume that treatability statements are made to communicate that something can be done, and to clarify what that is; treatment is conceived of as a tool to accomplish particular clinical goals, defined in specific, technical terms. Hence, physicians use treatability statements to convey that they can "do something." In treatability statements, technical concepts masquerade in everyday language.
