FABLIAU

A fabliau (plural fabliaux) is a coarse short tale related bluntly for humour. Well known examples are Chaucer's Miller's and Reeve's Tales.

Paraphrase and Precis

If you are asked to paraphrase a passage you rewrite it, at a similar length, in your own words. A précis of a passage, is a summary of its main points which reduces it in length, usually to one third of the original. To remember the difference, think of the word precise.

Summary and Summery

Summary means a brief  statement of the main points and summery refers to anything typical of summer.
Perhaps one way of remembering is that main begins with ma which recurs in the word summary.
