I cannot find an explanation for the use of gerund + of, such as:

  • planning of our future vacation;
  • producing of sound; etc.,

—versus the same without of.

I prefer without of.

Which is correct?

  • of is not mandatory in such cases, it can be elided without grammatical error. However, the definite article is not a substitute for the preposition here as is implied by the title of this post. By the way, where is the the in the example in the body of the question? – Kris Aug 05 '14 at 14:27
  • I understand the definite article is not a substitute. I was not sure how to stress that in the first case it is the accusative which follows while the latter one it is the genitive. When saying it is not "mandatory" I would appreciate to know when it is. – Miki Aug 05 '14 at 14:41

In answering your question it is helpful to start with an extract from the definition of gerund in The Oxford Dictionary of English Grammar (p178):

The noun-like and verb-like properties of the -ing form are on a cline.

Nouns are not followed by direct objects, so we cannot say:

*The planning my vacation (took a lot of time)

since planning in this case clearly functions as a noun by virtue of the inclusion of the determiner the. It needs to be followed by a prepositional complement:

The planning of my vacation (took a lot of time).

However, in the phrase:

Planning my vacation (took a lot of time).

planning takes on verb-like qualities, and hence can indeed be followed by a direct object. And of course verbs can be modified by adverbs, so you can say:

Carefully planning my vacation (took a lot of time).


In answer to OP's follow-on question in the comment: The definite article is typically used in front of a noun that is followed by a prepositional complement starting with of:

The cost of my vacation was very low.

*Cost of my vacation was very low.

The planning of my vacation took a long time.

*Planning of my vacation took a long time.
