תרגום - טורקית-ספרדית - hayatımın anlamısın

can we use "razón" instead of "sentido"?

"Razón" and "sentido" are synonyms in this expression, fuyaka. No difference in Spanish.

I asked to learn which one was appropriate.
actually,when i looked my dic in this morning i realized i had drivelled.they were completely different.
thanks a lot
