This quiz is for English learners at any level, and for native speakers who pause over two verbs that look almost identical. It starts with the past tenses you use every day and works up to the pairs that even confident writers mix up.
Each answer gives the three forms of the verb and points to others that follow the same pattern, so one answer helps you remember several verbs. Tip: learn irregular verbs in families that change in the same way rather than as one long alphabetical list.
