I want to know which part of speech completion is?

 

[SoothingDave]

It's a noun, isn't it? Words with "-tion" usually are. Object of the preposition "on."

Can I use completing (gerund) in the above sentence?

 

[Charlie Bernstein]

Yes, if you get rid of the of.

"...after completing the related tasks."

That's probably still true, though the habit of verbing nouns may change that.
You can proposition someone; petition someone; apportion blame; transition into a situation where you sanction something, etc.

 

[SoothingDave]

If this verbing carries on too much, I will revolution against it.

 

[suniljain]

It means completing is verb? With "ion" it was noun.

 

[MikeNewYork]

Technically, "completing" would be a gerund (a verbal). "Completion" is a noun.

[STRIKE]It means[/STRIKE] Does it mean "completing" is a verb? And with "-ion" it was a noun?

Please look at my corrections to your post.

 

[suniljain]

I understand verb can only be a gerund by adding "-ing" if we use the same after preposition.

Can you please also clarify why completion is noun and completing is verb?

 

[MikeNewYork]

A gerund is not a verb. A gerund (verbal) is a noun made from a verb.

I love those noun-to-verb transitions though. They are so useful and so easy.
