If you also want to allow a single letter as a word:

^[a-zA-Z]+(?:[\/ -][a-zA-Z]+)?$

Explanation

  • ^ Start of string
  • [a-zA-Z]+
  • (?:[\/ -][a-zA-Z]+)? Optionally match either / - and 1+ chars a-zA-Z
  • $ End of string

It is a bit hard to understand what you are looking for but it looks like what you want is something more like ^[a-zA-Z]+[\/\- ]?[a-zA-Z]+

You are missing is + after the [a-zA-Z] to indicate there is one or more, and then you need \ infront of - and / to escape
