Questions & Answers about Oletko liian uupunut leiriytyäksesi tänään?
How does leiriytyäksesi translate to "to make camp" here?
It uses the long first infinitive (the basic verb plus the translative marker -kse- and a possessive suffix). When paired with liian (too) and an adjective, it forms the standard Finnish structure for "too [adjective] to [verb]".
How does this "too X to Y" structure relate to the lesson's sen verran ... että structure?
They both express consequence and can often be swapped! You could rewrite this as Oletko sen verran uupunut, ettet jaksa leiriytyä tänään? (Are you so exhausted that you can't make camp today?). The long first infinitive with liian is simply a more compact way to express a blocking consequence.
Why does leiriytyäksesi have the -si suffix?
The long first infinitive requires a possessive suffix that matches the subject performing the action. Because the question is directed at "you" (oletko), the verb takes the second-person singular suffix -si. For "I", it would be leiriytyäkseni.
What kind of word is uupunut here?
It is the past active participle (the NUT-participle) of the verb uupua (to tire or become exhausted). While technically a verb form, it is functioning entirely as an adjective here to describe a state, which is a very common usage.
