What this suffix does
-chosen forms compound adjectives that evaluate the quality of a selection — whether of words, examples, people, or strategies. Well-chosen, carefully-chosen, poorly-chosen, ill-chosen, randomly-chosen — each compound judges not just what was chosen but how well the choosing was done. In literary and critical writing, "well-chosen" and its contraries are essential tools: a well-chosen example does more argumentative work than any number of poorly-chosen ones; a carefully-chosen word can change the entire meaning of a sentence. These compounds belong to the vocabulary of editorial and analytical judgment.
