Common collocations

• sine wave Noun + noun

Borrowed from Latin sinus ("curve, fold, bosom"), used to translate Arabic jayb ("bosom"). Jayb arose from a reading of consonantal j-y-b, representing Arabic jiba, itself borrowed from Sanskrit jya ("bowstring, chord"). The mathematical term is therefore the result of a historic translation chain.
