Learn Turkish: Yeter ki sunum etkileyici olsun, yatırım bulmak kolay. - As long as the presentation is impressive, finding investment is easy.

The phrase yeter ki (provided that / as long as) is conventionally followed by the optative or imperative mood to express a requirement or wish. While English uses a standard present tense ("is impressive"), the Turkish structure yeter ki ... olsun is a fixed pattern that literally means "suffice it that it be..."

Could we just say "Sunum etkileyici olursa..." instead of using yeter ki?

Yes, Sunum etkileyici olursa means almost the same thing ("If the presentation is impressive"). However, yeter ki adds strong emphasis, showing that this condition is the only thing that matters: "Just as long as the presentation is impressive (and nothing else matters)..."

How is the word etkileyici (impressive) formed?

It builds up from the noun root etki (effect/impact). Adding the verb-making suffix -le gives us etkilemek (to affect/impress). Finally, the suffix -(y)ici turns the verb into an active adjective, resulting in etkileyici (impressive / impactful).

Why is there no "to be" verb at the end of the sentence, like kolaydır?
