terms used in everyday life related to mental phenomena, but which also tend to be used in professional and academic discourse as thought they are technical terms, despite not being tightly defined
"There is then a kind of folk psychology of mind that permeates our own thinking (sic) and dialogue and which functions perfectly adequately in normal conversation, but which lacks the precision expected in technical communication. We might refer to this as the mental register, where key terms would include thinking, ideas, understanding, knowledge and beliefs. The mental register does effective work for us in everyday discourse in many communicative contexts, but when we need to specify more precisely what some of these terms refer to, we may soon run into difficulties." (Taber, 2013, p.29)
