Will pedants please stop ranting about the limitations of their own vocabularies.

method /ˈmɛθəd/ noun - a particular procedure for accomplishing or approaching something, especially a systematic or established one.

methodology /mɛθəˈdɒlədʒi/ noun - a system of methods used in a particular area of study or activity.

A prescribed "system of methods" is not the same as "method" or "methods".

Life and language moved on since the 1960s. Burying your head in the sand and bellyaching: "it wasn't a word when I was at school" won't change that.
