Sense: adjective/2

Toothless, powerless, ineffective, and weak all describe a lack of force or ability, but their focus differs. Toothless is metaphorical — it compares a rule or institution to an animal that cannot bite, and is almost always used about laws, regulations, or official bodies that lack enforcement power. Powerless is broader: a person, group, or even an emotion can be powerless ('She felt powerless to stop the closure'). Ineffective focuses on results — something that fails to achieve its purpose, often because of poor design rather than lack of authority ('The medicine proved ineffective'). Weak is the most general and informal, covering physical, personal, and institutional lack of strength ('a weak argument', 'weak coffee'). To say 'the law is toothless' suggests it exists but carries no real threat of punishment, while 'the law is weak' suggests it exists but is easily ignored or too lenient.

Etymology

Old EnglishMiddle EnglishEnglish

Toothless comes from Old English 'tōþ' (tooth) and '-lēas' (without, lacking). The literal meaning 'having no teeth' has been in use since the 12th century. By the early 20th century, the figurative sense 'ineffective, unable to enforce or punish' emerged, drawing on the image of a toothless animal that cannot bite or threaten. The idiom 'toothless tiger' — a thing that seems dangerous but is harmless — became popular in English during the mid-1900s, possibly influenced by the Chinese phrase 'paper tiger' (紙老虎).
