Which or Witch?
Which
Exemple : ‘’I don't know which pair of shoes I should buy.’’
"Which" and "witch" are pronounced very similarly and this can cause confusion. "Which" is pronoun or a determiner which is used in questions and structures where there is a determined or limited set of options to choose between. It is also often used in writing after a comma in order to provide extra information about something previously mentioned.
Witch
Exemple : ‘’I dressed up as a witch for Halloween. ’’
"Witch" is a noun referring to a woman who is believed to have magical powers. It generally is used in a negative sense, however, it is not exclusively reserved for only negative situations. Describing a person as "a witch" would be taken badly though!
