Error analysis is a type of linguistic analysis that focuses on the errors learners
make. It consists of a comparison between the errors made in the Target
Language (TL) and that TL itself. Pit Corder is the “Father” of Error Analysis (the
EA with the “new look”). It was with his article entitled “The significance of Learner
Errors” (1967) that EA took a new turn. Errors used to be “flaws” that needed to be
eradicated. Corder presented a completely different point of view. He contended
that those errors are “important in and of themselves.” For learners themselves,
errors are 'indispensable,' since the making of errors can be regarded as a device
the learner uses in order to learn.
