Morphology

summand = sum (transparent) = sum + and

The word 'summand' is directly related to the concept of 'sum', with the suffix '-and' indicating an element involved in the action.

Etymology

Summand comes from sum 'total' and the ending -and, a Latin ending meaning 'something to be done', so it names what must be done to the sum. So a summand is a number 'to be added' when you add numbers, one of the pieces that makes the total, much like the word addend.
