Sagot :
On utilise which pour les objets ou les choses non vivante et who pour désigner une personne
Par exemple :
"A detective is a person who investigates crimes" un détective étant une personne on utilise who.
"An alibi is an excuse which is used by a person to show that he was not on the crime scene"
Un alibi n'est pas une chose vivante donc on va utiliser which.
Les 2 signifient "qui" mais l'un désigne une personne et l'autre un objet, une idée ou juste quelque chose non vivante.
J'espère que ça t'aura aidé à comprendre les utilisation de who et which ;v;
A clue is a fact or an object WHICH helps to solve mysteries.
An evidence is something such as a witness statement or an object WHICH is used as a proof in a crime.
A witness is a person WHO can give an account of something that happened.
A weapon is an instrument WHICH is used to kill. A detective is à person WHO investigate crimes.
Sleuth is another word WHO means the same as detective.
An alibi is an excuse WHICH is used by a person to show that he was not on the crime scene.
A murderer is a man or woman WHO kills someone.
