I am doing a Cambridge Advanced English test this weekend. The free online test they provide online lets you transform words like this, from nouns to verbs to adjectives, back and forth.
• Come > overcome • Fit > fitness • Endure > endurance • Benefit > beneficial • Able > disability • Strong > strength • Type > typically • Severe > severity
Personally, I made the mistake in this one, writing "severeness" instead of severity. Are there any rules on such transformations or is it all about actually knowing the correct word? Can you recommend any resources to practice this?
