Prelationship is a relationship between people who are not yet but could become romantically involved. The two are probably seeing each other frequently and both have the intention to develop a romantic relationship. Maybe it is just a matter of time.

Prelationship指两人交往但还没有到正式恋爱的阶段。两人可能经常见面约会，并且都有意发展恋爱关系。或许只是时机还没有成熟。我们可以称之为“培养感情阶段”。

这个词是前缀pre和relationship的合成形式，表示是一段relationship开始之前的阶段。类似的词汇还有：prehistory（史前）、preschool（学前）、prepay（预付）等。
