Parenthesis has recently seen a considerable surge in interest. This volume presents the - often contrasting - theoretical positions on parenthetical verbs and examines them from different analytical perspectives.

First the good news - all new verbs in English are regular. However, that doesn't help you to learn the approximately 180 irregular verbs which do exist.

Other teachers think you should not learn them at all – you will just gradually acquire them over time.
