What is the difference between a gerund and a germino?

A gerund is a verb that ends in -ing and is used to form the present tense of a verb. A germino is a noun that is formed from a gerund by adding -o.

For example, the gerund "running" is used to form the present tense of the verb "run," while the germino "runner" is a noun that is formed from the gerund "running" by adding -o.
