Lambast → It is formed from 'lamb' (from Old English 'lamb', meaning a young sheep) and 'bast' (from Middle English 'basten', meaning to beat or strike). The word originally described the act of beating or striking, metaphorically used to mean harsh criticism or reprimand.
Think of 'lamb' as something gentle being 'struck' or 'beaten' ('bast'), which helps you remember that to lambast means to criticize harshly.
