I was taught this is a project management for engineers course I took when I was younger: never use language that is open to interpretation. In addition to your examples, I also see this happening in meetings when engineers say a non-sprint task will be "quick." How quick? A few minutes? A few weeks? A few quarters? As soon as we started clarifying these ambiguities we eliminated a lot of misunderstandings.
