Adinary Nuance

Synthetic is close to artificial, but it often sounds more technical and material-focused. Use synthetic for things made by humans, especially chemicals, fabrics, or products. Artificial can be broader and can also describe something fake, unnatural, or less real in feeling. In everyday English, synthetic may sound more neutral than artificial when talking about materials.
