Used to describe something happening after a particular point in time that was just mentioned.
“The trial period lasts 30 days; thereafter, the monthly fee applies.”
“New members pay a reduced rate for six months and the full rate thereafter.”
This formal word often follows a specific date or milestone in a diagram, describing what applies from that point onward (e.g., 'the first year is free; thereafter, the standard fee applies'). Identify the reference point first, then apply the thereafter condition to the rest of the timeline. It is a common paraphrase for 'after that' or 'from then on'.
Synonyms: after that, from then on, subsequently
