If you like the finer details of grammar and punctuation, then you're gonna love this episode.
We geek out on the subtle, but incredibly important and occasionally crucial differences between three little horizontal lines: the hyphen - the En Dash – and the Em Dash —
Jono explains hyphens for line breaks and compound terms, how usage can evolve into single words (e.g., wildlife, wellbeing), and why hyphen placement can change meaning (e.g., five-dollar bills). The en dash is described as linking ranges and relationships (pages, dates, times, scores, routes, debates, partnerships, negotiations), with notes on how to type it. The em dash is framed as a stronger-than-comma interruption for added thoughts, with style cautions and typing methods. They discuss underscore origins from typewriters, punctuation differences across countries, and how AI popularized em dashes as a telltale sign of machine-written text.
Most importantly though, we discuss why this matters and that if used correctly, they can help avoid misunderstandings.
