IPA: /ˈsɪəriəli/
KK: /ˈsɪr.i.əl.i/
In a way that involves a sequence or order, where things happen one after another rather than at the same time.
The tasks were completed serially to ensure each step was done correctly.
Serially → It is formed from "series" (from Latin "series", meaning a row or chain) and the suffix "-ally" (meaning in a manner relating to). The word "serially" means in a manner that relates to a series or sequence.
Think of a 'series' as a chain of events happening one after another, and the '-ally' shows how something is done. So, when you think of 'serially', imagine things happening in a sequence.
