The root pens comes from Latin and means “hang” or “weigh (out),” and by extension “to pay” or “to distribute.”

Core meaning

  • In Latin, pend-/pens- is tied to the idea of something being hung on a scale and weighed , which is why it also connects to ideas of value, payment, and distribution.
  • So when you see pens inside English words, it usually carries the sense of weighing, paying, or distributing something out.

Examples in words

  • Dispense – to distribute or “weigh out” something, like medicine or justice.
  • Dispensary – a place where things (often medicine) are “weighed out” or given out.
  • Compensate / compensation – to pay someone back, i.e., to “weigh” what is owed and give it.
  • Expense / expensive – related to what is paid out or costs a lot when “weighed” in money.
  • Indispensable – originally “not able to be set aside or done away with,” i.e., something whose value can’t just be “weighed out and given up.”
