Glad to hear it. Next time do not wait for grammar rules to eat, do it as you wish, never fallow the instructions.

I understand you very well. Usually I do not fallow the instructions.

Hi Bod,
This -dir suffix is the causative suffix.

Examples:
almak (to get) > aldırmak (to make somebody get)
bakmak > baktırmak (to make somebody look)
yapmak > yaptırmak (to make somebody do)

This issue is very smillar to passives:
germek (to stretch) > gerilmek (to be stretched)
bozmak (to break down) > bozulmak (to be broken down)

Now, the question is, "Is aldırmak a verb on its own or is it a variant of almak?" Smillarly, "Is 'gerilmek' a verb on its own or is it a variant of germek?"

These are a bit difficult to tell. My approach is to consider all those causative or passives as independent verbs. Therefore there is nothing wrong to say the infinitive of havalandırarak is havalandırmak.

In most cases the causatives or passives have different meanings then the version they were derived from. This means the causatives ort passives have such meaning that are not included in the definition of non-causative or non-passive versions. Those causative and passives need their own definitions. They are independent verbs. In some cases a verb might be omited from language but its passive or
causative verb can survive.

On winmekmak we couldn't prevent passives to take passive a second time. There is no causative conjugation at all so the problem was only with passives although the issues are the same.
