Remember, that when we are talking about conjugating verbs, there are regular verbs and irregular verbs. All verbs (regular and irregular) have the same endings. But there can be many differences in the root or stem of the verb.

Irregular verbs are verbs that have these changes in the root or stem of the word.

As you may have noticed, some irregular verbs can be grouped together. In these cases the verbs are NOT grouped by meaning or purpose, but rather just in the way that they are spelled.

Irregular verbs with changes in the first-person.
