For a purpose to be manner specific, according to Mag Uidhir, is for it to be essentially constituted both by an action (or state of affairs) and a manner, such that the purpose is to perform that action (or bring about that state of affairs) in that particular manner. A purpose is manner inspecific, on the other hand, if failure to perform the action (or bring about the state of affairs) in the prescribed manner does not necessarily constitute failure to satisfy the purpose.
