tick
This word evokes a sense of precision and brevity, whether referring to the mechanical rhythm of a clock or the quick action of marking a checklist. It carries a neutral to positive connotation of efficiency and correctness when used as a mark of completion, but shifts to a negative, parasitic association when referring to the arachnid.
In British English, the term is used specifically in financial contexts to describe credit arrangements, as in buying on tick. This usage is distinct from the temporal meaning, though both rely on the idea of a small, discrete unit of measurement or recording.
