Learn Finnish: Jos sinulla on rahaa, sinulla on varaa hemmotella itseäsi. - If you have money, you can afford to pamper yourself.

This is the core structure for expressing capability or having the resources to do something. It uses the possessive structure (sinulla on, "you have") plus a resource noun in the partitive (varaa, from vara, meaning "means" or "funds"), followed by a first infinitive (hemmotella). Literally, it translates to "you have the means to pamper".

Both rahaa and varaa are partitive. Are they partitive for the same reason?

Yes, essentially. In Finnish possessive sentences, the thing possessed is put in the partitive if it is an uncountable mass or abstract noun. Just like rahaa (money) is an uncountable mass noun, varaa (affordability/means) acts as an abstract, uncountable resource here.

Why is the reflexive pronoun itseäsi ("yourself") in the partitive case?

It is the object of the verb hemmotella (to pamper). Hemmotella is a partitive verb, meaning it expresses an ongoing action, an emotion, or an action without a clear endpoint, so its object must always take the partitive case (itseä).
