The word 'sudsiest' is derived from 'suds' (from Old English 'sūde', meaning a frothy liquid or soap) and the suffix '-iest' (meaning most). Thus, 'sudsiest' refers to something that has the most suds or foam.
Think of 'suds' as the frothy bubbles you see in soap, and remember that 'sudsiest' means having the most bubbles or foam.
