Learn Turkish: Nasıl olsa maketi kesme tahtasında keseceksin. - You will cut the model on the cutting board anyway.

Kesme is the short verbal noun of kesmek (to cut). When combined with tahta (board), it forms the purpose compound kesme tahtası (cutting board), utilizing the possessive suffix -sı. To say "on", we add the locative suffix -da. The -n- in between is a buffer letter, which is always required when attaching a spatial case suffix to a noun compound ending in a possessive suffix.

What is the literal meaning of nasıl olsa, and how is it used in this sentence?

Literally, it means "how(ever) it may be" (nasıl + ol-sa). In practice, it is a common fixed phrase meaning "anyway," "in any case," or "regardless." Here, it sets up a tone of inevitability, implying "Since you are going to cut the model regardless, you will do it on the cutting board."

Why does the word maket take the -i suffix to become maketi?

The -i is the definite accusative case suffix. Because the speaker is referring to a specific, known model ("the model"), rather than just cutting models in general, it needs this case to mark it as the specific direct object of the verb keseceksin.

Does it sound awkwardly repetitive to a Turkish speaker to use kesme and keseceksin in the same sentence?
