Question

What is the comparative and superlative degree of active
​

Answer 1

Comparable: more active

Superlative: most active

Answer 2

However, there are some of these short adjectives that can only take 'more/most'. For example, the comparative form of 'active' is 'more active' instead of 'activer'. There are even some of these adjectives that can either take 'more/most' or '-er/-est'. For example, 'commoner' and 'more common' are both acceptable.
