The correct version will be:
intend
not only to win but also to break the world record; quite frankly, my opponent is
neither a threat to me nor an intimidation to
anyone.This is purely a test of parallelism in the use of co-relative conjunctions.
1 an infinitive verb - [highlight]to win[/highlight] - after not only, should be verbatim paralleled by another infinitive [highlight]to break[/highlight] and not just break.
Similarly, the use of a noun - [highlight]a threat[/highlight] - after neither demands another noun after nor. Use of [highlight]quite frankly[/highlight] after nor is a wrong word order breaking the parallelism. Again i[highlight]ntimidating to anyone[/highlight] is not as elegant as [highlight]intimidation to[/highlight] any one.
A gerund is preferred only when you have no other appropriate forms of noun.
For example, the gerund
singing has no appropriate alternate noun forms.
Listening and
hearing are similar such words, where we have no recourse to other regular nouns. But it is not proper to use
constructing in the place of
construction or
educating in the place of
education.
