Shrewder is derived from the adjective "shrewd" (from Middle English "shrewd", meaning bad, evil, or ill-disposed), which itself may have roots in Old English "scrēawian" (meaning to curse or to scold). The suffix "-er" indicates a comparative form. Thus, "shrewder" means more shrewd or possessing greater astuteness or cleverness than another.
Think of someone who is more clever or astute than others — the suffix '-er' shows comparison, and 'shrewd' originally referred to someone with a sharp or cunning nature.
