Will you please explain to me the difference between 'usage' and 'use'? For instance, how would you say: usage of the word 'consumption' or use of the word 'consumption'?
USAGE and USE - Terms used by Widdowson (1978) to refer to two aspects of communicative performance
a) the ability to produce correct sentences, or manifestations of the linguistic system = USAGE.
b) the ability to use the knowledge of the rules for effective communication = USE.
Objectives- the aims, what you wish the students to learn
Competencies- what you want them to be able to do with the language- putting their learning into action; you measure the success of the learning by the ability to do things with the language, so it moves away from traditional assessments

‘The usage of American spellings in British publications is to be deprecated,’ ‘The usage of water for washing cars is forbidden.’ Incorrect. The word required is use.
Usage means ‘that which has become customary’ or ‘that which has been established by long- standing use. Thus, though ‘it is me’ violates the grammatical rule that the verb to be should be followed by a complement in the nominative case, it has become established by usage, and must therefore be accepted.
There cannot be a wrong usage of a word, but there may be a wrong use of it.
