Comparative: slinkier
Superlative: slinkiest
Slinkier → The word 'slinkier' is derived from 'slink' (from the Old English 'slinkan', meaning to move stealthily or to creep) and the comparative suffix '-ier' (indicating a higher degree). Thus, 'slinkier' means more stealthy or more inclined to move in a sneaky manner.
Think of someone who moves 'stealthily' ('slink') and is 'more' so ('-ier') — that's why slinkier means more stealthy.
