Weaker → It is formed from "weak" (from Old English *wēac*, meaning not strong) and "-er" (meaning more). The word "weaker" means more lacking in strength compared to something else.
Think of someone who is 'not strong' ('weak') and the '-er' indicates they are 'more' so. This helps you remember that 'weaker' means someone or something that is more lacking in strength.
