One hill I will die on: bi-weekly should only ever mean twice a week. Semi-weekly (or fortnightly) is for once every two weeks.

I will mute everyone who disagrees and pretend they never existed

Checked Italian Treccani dictionary and seems that “twice” is the only definition. The Cambridge dictionary is more confusing imo as you can see.

I think the cognitive hurdle comes from people assigning the prefix "bi" (meaning "two") to the word "weeks", leading to "every two weeks" in their heads.

When in reality, the prefix "bi" applies to the word "weekly", which is a *rate* and not a unit of time.

Hence, the correct interpretation is "two weekly" or, in better English, "twice weekly".
