For info, the British word for a 200th anniversary is 'bicentenary'.

Bicentennial is an adjective not a noun though, which is why bicentenary is the actual answer to the question.

Bicentennial is also a noun in American English, as nonsensical as that seems to Brits like us.

A. Bi is already a common abbreviation for Bisexual so it was in the forefront of many’s minds already

B. The Bicycle question was worded weirdly and wasn’t as immediately obvious as the bisexual question.

Would occurring every 14 days not be " bimonthly" ? Biweekly implies something is occurring twice a week ?

The proper English word would be 'fortnightly' - nice and clear. Shame it doesn't begin with 'bi-'.

Fortnightly - occurring every FOURteen NIGHTs. Pretty straight forward and logical to me.

Semi-monthly is twice per month, which is close to biweekly, but not the same. If you get paid semi-monthly, you get 24 paychecks per year. If you get paid biweekly, you get 26 paychecks per year.

Not at all. Biweekly means every two weeks. Bimonthly means every two months. I've subscribed to enough bimonthly magazines to know.

I would say "supported by both Republicans and Democrats" is the least common usage of that word, and mention of Reps and Dems makes it too USA-specific.

The word can mean "comprising both political parties" when referring to committees, or even "independent of any one political party".

+10
Level 81
Nov 14, 2020
Agreed. "Supported by two/both parties" is a far more accurate definition, plus it makes it geographically-neutral. The word is used all over the world, and is in no way tied to the US political system.

Hear hear. I missed this one because of the overly narrow specification, though I'm familiar with bipartisanship. Let all our parties work together to encourage a tweak to the clue :)

Mar 11, 2023
I agree, but... As a point of order, "independent of any one political party," is NON-partisan, not bipartisan. I know that is slightly pedantic, but in a few instances it can really make a difference.

"One attracted to either men or women" technically means someone who is only attracted to one sex or the other. I think you mean "One attracted to both men and women."
+1
Level 74
Feb 16, 2023
I agree. It's probably best to phrase it more specifically as, "one who can be attracted to men or women," or "one who can be attracted to both men and women."

After a quick google search of 'do birds have feet' I found that almost all of the sources refer to the things on the end of birds' 'legs' as feet. It also referred to the appendages as toes.

Bisexual means to be attracted to 2 genders. Those genders don't necessarily have to be men and women, and the wording of the clue implies that a bisexual person is attracted to either men or women, when they would actually be attracted to both at the same time

I can't believe nobody pointed this out yet, but bipolar and manic depressive are not the same thing. I had this on one of my April Fools quizzes.

Bipolar disorder and manic depression are indeed the same thing. (I've just looked up your quiz. Your trick question leaves out the depression bit.)

Yes. The two describe the same condition. There are many sub-variations but only one condition.

I got them all except for the tooth. I must say, on this side of the Atlantic (E. side), I've never heard them called that - they are premolars. Indeed, it is normal for some of them to have more than two cusps.

Level 70
Apr 9, 2019
Bisexual means exactly the opposite of being either attracted to men, or to women. It means to be attracted to both. If you are attracted to either men, or women, you are heterosexual or homosexual depending on your own sex. Quite a big mess/mix up imho. (Like saying that a guy that likes women is homosexual)
+6
Level 89
Mar 31, 2020
I thought the same thing. The clue should read "attracted to both men and women."
+3
Level 76
Feb 28, 2020
I have never heard the term "Bicuspid" I have learned and always heard them called "canines"
+2
Level 84
May 8, 2022
The bicuspids are, more specifically, between the canines and the molars and are usually referred to as premolars.

Same. I typed in 'Bigamy' 'Bilygamy' 'Bigamous' 'Polygamy' and 'Polygamous' before I ran out of time.

Level 79
Jan 25, 2023
could "to cut in two" also be 'bifurcate'?
+1
Level 92
Jan 25, 2023
Perhaps. In my mind bifurcation typically implies a separation and also a copying, so you end up with 2 wholes instead of 2 halves. That may be entirely connotation though, and not in the denotation of the term.
+1
Level 84
Jan 25, 2023
To bifurcate is to fork or split into two branches which are still attached. Like a snake’s tongue.
+4
Level 66
Jan 25, 2023
The bigamist clue really threw me because it is not a correct definition. A bigamist is someone who illegally has more than one spouse concurrently. The spouses don't have to be wives, and there can be more than two. Legality is an essential part of the definition, because in some times and places multiple marriage has not been classed as bigamy.

Did you manage to guess the right answer, despite the colossal red herrings?

Level 74

I think bicuspids are the ones between molars and canines, not incisors.

Couldn't the trade agreement also be "binding"

It comes from bind-ing, not bi-nding or bi-inding. Not the root for 2.

Small error I’m slightly surprised hasn’t been noticed yet: “Older aircraft with twos sets of wings” seems to have pluralised the number as well, like it’s been translated overly-literally from a language like French or Spanish.

Is there a lack of consistency if you accept bicep for biceps and bifocal for bifocals but not binocular for binoculars?
+1
Level 59
Mar 6, 2023
You don't accept pant for pants or scissor for scissors.
+3
Level 77
Jul 20, 2023
Then why accept "bicep" for "biceps" and "bifocal" for "bifocals"?
+1
Level 78
Jan 31, 2024
because there is no such word as binocular. I mean there is, but it's an adjective and not the noun form that the clue is asking for. Same for bifocals. If it accepts bifocal, that seems like an error to me.
+2
Level 78
Jan 31, 2024
Please accept bifurcate in addition to bisect. Both mean to divide in two.
