取り上げるのは、reciprocal /rɪsíprək(ə)l/ です。以下で意味等を確認していきます。
LDOCEには、“a reciprocal arrangement or relationship is one in which two people or groups do or give the same things to each other” とあり、『ウィズダム英和辞典』には、「（関係・取り決めなどが）相互の、互恵的な」と載っていました。
続いて、ODEで語源を調べてみると、“late 16th cent. : from Latin reciprocus (based on re- ‘ back’ + pro- ‘forward’) +-AL.” と定義されていました。（Otoyo）
