To reduce or balance the effect of something unwanted by exerting an opposite force or effect.

From L. compensatus, p.p. of compensare "to weigh one thing (against another)," thus, "to counterbalance," from → com- "with"+ pensare, frequentative of pendere "to weigh, to hang."

Pâhangidan, from pâhang (Dehxodâ) "that which is put in a balance scale to equalize the weights," from pâ- variant of pâd-, → counter-, + hangidan variant of sanjidan "to measure; compare, put in balance," → object.
