This adjective describes what is unsuitable or inconvenient for a purpose. Luke uses it in Acts 27:12 to describe the harbor at Fair Havens as unsuitable for wintering. The term appears in practical contexts for locations or arrangements that don't serve their intended purpose well. English 'unsuitable,' Spanish 'inadecuado' (inadequate), and French 'incommode' (inconvenient) all emphasize the mismatch between the harbor and the sailors' needs. German preserves the Greek form, perhaps because the rare word has no perfect German equivalent.
