Combinatorial → It is formed from "com-" (meaning together) and "binare" (from Latin, meaning to pair or to double), along with the suffix "-al" (meaning relating to). The word "combinatorial" refers to something that relates to the combination or arrangement of elements together.
Think of elements coming 'together' ('com-') to 'pair' or 'double' ('binare') — that's why combinatorial relates to the arrangement of combinations.
