  The form method as popularised by Lions and Kato is a successful device to
associate m-sectorial operators with suitable elliptic or sectorial forms.
McIntosh generalised the form method to an accretive setting, thereby allowing
to associate m-accretive operators with suitable accretive forms. Classically,
the form domain is required to be densely embedded into the Hilbert space.
Recently, this requirement was relaxed by Arendt and ter Elst in the setting of
elliptic and sectorial forms.
  Here we study the prospects of a generalised form method for accretive forms
to generate accretive operators. In particular, we work with the same relaxed
condition on the form domain as used by Arendt and ter Elst. We give a
multitude of examples for many degenerate phenomena that can occur in the most
general setting. We characterise when the associated operator is m-accretive
and investigate the class of operators that can be generated. For the case that
the associated operator is m-accretive, we study form approximation and Ouhabaz
type invariance criteria.
