関係がある・～に関して: "Involved with/connected to X"

Introduction

Relationships, love 'em or hate 'em, they're a part of life. And learning how to talk about them is an important part of learning Japanese!

Today, we'll cover how to say that things are "connected" to other things, or that there's a "relationship between X and Y".

Sounds awesome right? Right???

～関係かんけい（が・の）ある: There is a connection; it's undeniable

構成こうせい

• 

  Nounと・に(は) + 関係かんけい（が・の）ある
  Example:
  → バナナ王国おうこくには一切いっさい関係かんけいがありません。
  "(I) have absolutely no connection to the Banana Kingdom.”

The ～関係かんけいがある pattern is simply 「関係かんけい ("relation; connection") + the が particle + ある」, and is all about expressing that "there is or isn't a connection between X and Y."
