Oh tunci, dear bro,

I think you should step back and accept you are wrong.

I have a feeling that you misunderstand those top turkish language authorities and TDK.

I will seriously doubt that you cannot even undertand a simple sentence like this:

Gerund is verbal form that functions as a noun. This is the definition of gerund in English. So what would you call it in Turkish?

"isimfiil", no?

Appreantly you must have misundertood something here.

Gerund is a non-finite verb form, serving as a verbal noun. And we call verbal nouns "isimfiil" in Turkish.

Here´s a brief of the correcr English terms for others:

Gerund: a verbal form that functions as a noun ("isimfiil" in Turkish)

Gerundive: denotes verbal adjectives ("sıfatfiil" in Turkish), verbal adverbs ("zarffiil" in Turkish), or certain finite verb forms. The word comes from Latin gerundīvus ("of a gerund"), which is from gerundium ("gerund"), derived from gerundus, which is itself the gerundive of gerō ("carry, bear, carry out").

So the correct English term for what tunci (or mikex) incorrectly call gerund is gerundive.
