Learn Turkish: Onu püskürtmek olağanüstü bir marifettir! - Repelling it is an extraordinary feat!

When a verb acts as the general subject of a sentence, like 'repelling' or 'to repel' does here, we typically use the full -mAk infinitive. If it were taking possessive or case suffixes, we would use the short -mA form instead.

Why is bir placed after the adjective olağanüstü instead of before it?

In Turkish, when an adjective modifies a noun alongside the indefinite article bir, the standard order is [Adjective] + bir + [Noun]. So it is olağanüstü bir marifet, not bir olağanüstü marifet. This differs from English and is an easy trap to fall into!

What exactly does the -tir suffix do at the end of marifettir?

It acts as a generalizing copula (often called the factual 'is/are' suffix). While the sentence would still mean 'it is an extraordinary feat' without it, adding -tir gives it a stronger, more declarative, or objective tone, emphasizing that this is an established fact.

How is the word olağanüstü formed?

It is a compound of olağan (usual/ordinary) and üstü (its above/over). Literally meaning 'above the ordinary', it translates to 'extraordinary'. You will see this -üstü pattern in other common words, such as doğaüstü (supernatural).
