Similar case in point: “bimonthly” means “twice a month.” That makes sense.
But the definition for “bi-weekly” does not make sense.
What do you think?

I never heard that semi meant 1/2. I’ve always thought of semi as rather vague tbh. Meaning that there is no set amount of time between things.
bi- means two, as in bicycle: two wheels (circles)
semi- means half, as in semicircle: half of a circle
The problem is that the prefixes can be parsed as affecting either duration/interval as in (bi-week)ly, every two weeks, or frequency as in bi-(weekly), two times weekly. The same applies to semi-.
Personally I find the frequency interpretation a bit of a stretch—“two” is not the same as “two times” or “twice”—so I would tend to read e.g. bimonthly as every two months rather than twice each month.
You can bisect a circle to make two semicircles!
But if it’s semicircular…
bi-sect: cut into two parts; from Latin “bi-”, two, and “secare”, to cut.
The “sect” part is critical. “bi-” on its own doesn’t imply division.
Heh, yeah, I’m just messing with people here 😆
(This language confusion is mildly amusing, in the apparent inherent ambiguity we’ve created)
