Usage & Nuances
Very common in formal, academic, business, and everyday English. Common patterns: 'have an impact on', 'make a big impact', 'environmental impact'. As a verb, 'impact' is used too, especially in formal contexts ('The change will impact sales'), but some speakers prefer 'affect' in careful writing.
