Runny → The word 'runny' is derived from the verb 'run' (from Old English 'rinnan', meaning to flow or move swiftly) with the addition of the suffix '-y' (meaning characterized by). Thus, 'runny' describes something that is characterized by flowing or moving like a liquid.
Think of something that 'flows' ('run') and is 'characterized by' ('-y') that flow — that's why we say something is runny when it has a liquid consistency.
