põhiliisekspõhiliseks

Põhiliisekspõhiliseks is a term that appears to be a portmanteau of two Estonian words. "Põhiline" translates to "main," "basic," or "fundamental." "Liis" is a common Estonian female given name. The suffix "eks" can indicate purpose or destination, and "põhiliseks" is the allative case of "põhiline," meaning "into the main" or "for the main." Therefore, "põhiliisekspõhiliseks" could be interpreted as something akin to "for the main purpose of Liis becoming the main" or "for the main path of Liis."

The exact meaning and context of this phrase are unclear without further information. It is not a standard or commonly recognized idiom in the Estonian language. It is possible that this is a neologism, a personal expression, or a term used within a specific, limited group or context. Without additional details about where this phrase was encountered or its intended use, a definitive explanation remains elusive. Its construction suggests a deliberate, albeit unusual, combination of existing linguistic elements to convey a specific, likely nuanced, idea.
