As stated above the main rule is that for every verb in English, there is only one form of it in the past tense. The only exception is the verb "to be."
Wanted is used as the past tense for all subjects/pronouns.
So you just have to learn one word to be able to use it in the past tense. In this case we just needed to learn the one word "wanted," which can be used for all subjects or people.
To change a regular verb into its past tense form, we usually add ed to the end of the verb.
play – played
cook – cooked
rain – rained
wait – waited
For some verbs, we don't just add ed. These are irregular verbs. There is still only one form of these in the past tense.
"Went" (the past tense of "go") and "did" (the past tense of "do") are two of the most common irregular verbs.
