The term 'limitless quantities' can be represented by two crossword solutions: SEAS and INFINITIES. SEAS stands for 'Something Endless and Abundant Supplies', which implies that there is an abundance of something that never runs out. INFINITIES refers to the concept of infinity, which is a number that is greater than any other number and has no end. This suggests that the quantity of something is infinite and cannot be measured. Together, these two solutions represent the idea of limitless quantities, which means that the amount of something is so great that it cannot be counted or measured.
