not working correctly; defective
Not working in the right way because something is wrong with it inside.
Schéma d’usage :
faulty [equipment/system/part]
Erreur fréquente :
Learners often use "broken" for any problem, even when the thing still works sometimes. Use "faulty" when something works badly or unsafely because of a defect inside, especially for machines, parts, or systems (e.g., "faulty wiring", not usually "broken wiring").
Synonymes
defective (Slightly more formal and commonly used in technical or legal contexts.)

|
broken (More general and informal; often suggests physical damage or something that does not work at all.)

Having mistakes that make it not correct or not good to use.
Schéma d’usage :
faulty [reasoning/data/memory/assumption]

Synonymes
incorrect (General word for not correct, without focusing on why it is wrong.)
|

|
unsound (More formal; often used for arguments or logic that are not based on good reasons.)

Having problems in your character, such as weak or bad qualities.
Schéma d’usage :
