The simple past tense of the verb ‘want’ is ‘wanted’.
To explain further, verbs change form to indicate the time of action. In this case, ‘want’ is in the present tense, which refers to a desire or wish that is happening now. When we want to express that this desire was present in the past, we use ‘wanted’. For example, if you say, ‘I wanted a toy last Christmas,’ you are indicating that at that specific time in the past, you had a desire for a toy. The change from ‘want’ to ‘wanted’ indicates that the action is no longer occurring in the present moment.
