You know the verb, but which adjective do you need? English word families can help you express an action, tendency or characteristic more precisely: 🔁 repeat → repetitive “My work became repetitive because I completed the same task every day.” ⚡ act / action → active “She plays an active part in the project.” 💥 destroy → destructive “The storm had a destructive effect on the coastline.” The ending -ive often appears in adjectives, but you cannot add it freely to every verb or noun. The spelling and stem may change, so learn each adjective as part of a word family.
