What are diagrams used to represent the time coverage of a verb tense called?

• A. Time lines
• B. Bar charts
• C. Flow diagrams
• D. Word maps

Answer: (A)

Timelines are diagrams that place time on a line and show when an action occurs relative to a reference point. They’re ideal for visualizing how a verb tense covers time, because you can mark the present moment and indicate whether the action happens at a single point, stretches over a period, or extends into the past or future. This makes differences between tenses clear—for example, a point on the line represents a simple past moment, while a span up to now shows the present perfect.

Compared with bar charts, which convey quantities, or flow diagrams, which map steps in a process, or word maps, which show relationships between words, timelines directly encode temporal relationships. In language learning, seeing verb tenses plotted on a timeline helps you grasp how each tense relates to the reference time and to other tenses.
