Answer:

Explanation:
Nominalization or nouning is the transformation of verbs into nouns. Most times, such a transformation will require some alteration or other to be made, mostly through the use of suffixes, which changes the ending of the original word. However, there are nominalizations that require no change at all, the difference between verb and noun being revealed through context.
Some common suffixes for nominalization are -ation, -ance, and -ment.
Having that in mind, let's change the verbs given in the question into nouns:
1. to act - action
2. to fail - failure
3. to permit - permission
4. to lose - loss
5. to think - thought/thinking
