Meanings

1 Mutual — Given and Received Equally by Both Sides (Adjective) Very Common ▼

This meaning is about something that goes both ways — if you give it, you also receive it. Imagine two countries agreeing that their citizens can travel freely to each other’s territory without a visa. Country A opens its doors to Country B, and Country B does the same in return. This is a reciprocal agreement — both sides give and receive equally. You might hear “the deal was based on reciprocal trust” or “they had a reciprocal arrangement where they covered each other’s shifts.” Or think about a friendship where both people support each other through hard times — not just one doing all the giving. The word suggests balance, fairness, and mutual exchange. ✏️ Common pairings include “reciprocal agreement,” “reciprocal respect,” “reciprocal relationship,” and “reciprocal trade” — especially in formal or diplomatic contexts.

Vivid Example

The two universities signed a reciprocal exchange programme last spring. Students from each school could study at the other for a semester. It gave everyone the chance to experience a completely different academic culture.

2 A Number That Produces 1 When Multiplied by Another (Noun) Specialized ▼

This meaning is about a specific mathematical concept. Imagine your maths teacher writes the number 4 on the board and asks “what’s the reciprocal of this?” The answer is ¼, because 4 × ¼ = 1. This is what a reciprocal is in maths — the number you multiply by to get exactly 1. You might hear “the reciprocal of 5 is 0.2” or “to divide by a fraction, multiply by its reciprocal.” Or think about a student learning algebra and being told to flip a fraction upside down — that flipped version is the reciprocal. The word points to a precise inverse relationship between two numbers. ✏️ In everyday English, you’ll rarely hear this meaning — it belongs almost entirely to maths classrooms and textbooks.

Vivid Example

The teacher asked the class to find the reciprocal of each number on the worksheet. Most students got it quickly once they understood the trick. You just flip the fraction, and the answer practically writes itself.
