Etymology

From Middle English differren, from Old French differer, from Latin differō (“carry apart, put off, defer; differ”), from dis- (“apart”) + ferō (“carry, bear”). Compare Ancient Greek διαφέρω (diaphérō). Doublet of defer and dilate, see also infer, confer and collate, refer and relate, as well as prefer and prelate among others.

From diff + -er.
