Learn Finnish: Sinullakaan ei ole jano. - You are not thirsty either.

In Finnish, the clitic -kaan (or -kään) attaches directly to the word it emphasizes. Here, the emphasis is on you (meaning 'You aren't thirsty either'), so it attaches to Sinulla to make Sinullakaan.

Why do we say Sinullakaan instead of using the basic word for you (Sinä)?

Finnish does not use the verb 'to be' for physical feelings like hunger, thirst, or being cold. Instead, it uses the 'I have' structure: the person is in the adessive case (-lla or -llä) followed by the verb olla (to be) and the noun for the feeling. So, 'you are thirsty' is literally 'on you is thirst' (sinulla on jano).

Why is the negative verb ei ole used here instead of et ole?

Because this sentence uses the 'I have' structure, the verb olla is always in the third-person singular (on, or ei ole in the negative). The literal translation is 'Thirst is not on you either', so the verb stays in the third person rather than changing to et to match 'you'.

Could I use -kin here instead of -kaan?

No. The clitic -kin means 'also' or 'too', but it is only used in positive sentences (like Sinullakin on jano - 'You are thirsty too'). Because this sentence is negative, you must use the negative equivalent, which is -kaan (or -kään).
