The Greek adjective aneuthetos means 'not well-placed,' 'unsuitable,' or 'inconvenient.' It combines the alpha privative with euthetos ('well-placed, fit'). It appears once in the New Testament, in Acts 27:12, where it describes the harbor of Fair Havens as unsuitable for wintering.
Acts 27:12's single use of aneuthetos situates the word in one of Scripture's most detailed nautical narratives. The sailors' judgment that Fair Havens was unsuitable led them to press on against Paul's Spirit-guided warning, precipitating the devastating storm.
The narrative teaches that practical judgment without prophetic discernment is insufficient. The majority overruled Paul's Spirit-guided warning, preferring their own assessment of what was 'suitable' over divine guidance — a principle that applies broadly to the Christian life.
