As the design and development teams are finalizing the designs of widgets, controls, labels, you need to come together on the vocabulary: is it a dropdown menu, droplist, pulldown list, or something else? Establishing consistency of lingo is key towards more efficient, clear communication with minimal confusion downstream at spec’ing and QA’ing stages.
And part of the consistency might mean the designer has to suck it up and “drink the kool-aid” of the client company and use their legacy lingo particular to their customers and culture. I prefer the analogy of “when in Rome…do as the Romans do”, as “kool-aid” has a rather grim origin :-)
