Nope. Infirm is an adjective. An invalid is a noun.

Seriously? I guessed "itinerant" instead of "itinerary". *Slaps forehead*

I thought itinuary. Only ever have heard the word spoken (and and maybe 4 times at most) and never written.. I tried variations, but didnt get it right

Easiest of all the vocab quizzes. I only missed 4 (ibis, isthmus, incandescent, and implode). And ibex is a type of goat, i'm pretty sure. Not antelope, and it doesn't live in Africa, I don't think.

Level 62
Apr 23, 2018
Some variety of Ibex are found in Africa, but most aren't.

Ibex are members of the goat family & are not antelope.

I'd edit it to say 'ice covering a pole', since the way it's written implies some sort of iceage/nuclear winter.

I couldn't figure out how to spell iridescent...duh, was incandescent. Got at the last second!

Isn't igloo short for igluvigak....should take the full word, don't you think?

Spent ages trying to think of the verb pertaining to inquisitor, until...
+1
Level 62
Apr 23, 2018
I would say that "The Inquisition" was a form of aggressive questioning, but "inquisite" doesn't carry the same aggresive connotation necessarily.
+1
Level 64
Apr 23, 2018
How about an "exquisite exquisition?"
+2
Level 86
Jan 11, 2022
No one expected that.

Infidel could be added

Couldn't think of "inn". Guess I don't need to bother submitting my Mensa application.

Level 75
Apr 23, 2018
Don't feel bad, I couldn't figure out why imperical wasn't accepted for the empire clue and finally gave up. (I think my brain sort of combined imperial and empirical and came up with a rotten egg that wouldn't go away.)

Fine. No room at the inn.

Inn Is A house
+2
Level 62
Apr 23, 2018
"Inn"terestingly, Inn does come through old English for a dwelling place (in which case "house" would fit), but in modern English the closest thing to "house" that could be part of the definition is as an alehouse or public house--in other words a tavern or bar. In American English an Inn is usually a motel or hotel, and only occasionally an eating or drinking establishment.

An invalid isn't per se confined to his/her home or bed.. A lot of invalids are mobile, through a wheelchair etc.
+4
Level 75
Apr 23, 2018
I've always hated that word. Is it the opposite of valid? Most invalids I know are very valid people.
+1
Level 64
Apr 23, 2018
Is "invalid" still used? We don't say "crippled" anymore either.
+3
Level 68
Apr 2, 2021
Yes, I'm not sure either that the definition really fits.

My first thought was immobile.

Indecipherable should be accepted alongside illegible; they both relate to unreadable handwriting

came here to say this. Indecipherable means not able to be read or understood which seems like a pretty solid word for what bad handwriting is.

incomprehensible?

My brain jumped to ‘infant’ as a newcomer to a country although I knew perfectly well and it wasn’t what QM was looking for

Would you accept "irritating" for Incubus?

How/why does it say I got 50% on some of my answers, when I got all of them right?

Did you get them wrong on your first try? It tells you your cumulative percentage from all your tries.

i don't think "collapse" is the right way to describe an implosion. totally threw me off.
+3
Level 69
Dec 17, 2018
Same here, it made me think of a person collapsing. Not the opposite of explode. Anyway, collapse is downwards, (or more precise, the result of gravity, after whatever kept it upright, ceases to do so ( sorry for my english, havent slept in days like 2 hours a night and have a fever, cant construct the best sentences atm..) . while implode is an inward force
+4
Level 76
May 9, 2019
The description for "implode" is incorrect, and the one for "invalid" is vague and highly debatable. If a person is under house arrest, are they invalid?
+2
Level 69
Nov 28, 2019
Yea I tried incarcerated and immobile. Even if you want to use the rather unpleasant sounding term invalid, most people can get everywhere eventhough it might take more effort and/or some helpfull items..

Do you think that irrigation could count as irrigate?

Level 65
Jun 27, 2020
Really enjoyed this quiz - had me thinking very hard on some of them.
+1
Level 70
Sep 26, 2020
Given what happened this year I think you might want to change the description for 'invalid'
+2
Level 65
Oct 27, 2020
For the Invalid question, wouldn't Infirmed work as well?
+1
Level 78
Mar 9, 2022
I think I'll always remember incubus and succubus as a result of watch the 'Burbs--such a great movie.
+1
Level 65
Mar 28, 2022
Agree with others that definition for “implode” is inadequate. Could be improved by changing “violently collapse” to “violently collapse inward”.
+2
Level 60
Jul 9, 2022
Infirm? Immobile? Inambulatory?
+1
Level 75
Jul 10, 2022
adjective, adjective, not a word
+3
Level 63
Jul 13, 2022
Was wondering why it wasn't accepting Ibex - I thought maybe I was spelling it wrong. But yeah, I guess Impala is significantly more applicable.
+1
Level 33
Jul 22, 2022
Could maybe accept invade for relating to an empire...
+1
Level 79
Feb 9, 2023
Hey QM. I realise this is a very old quiz, but I have to question the clue for invalid. An invalid is not necessarily confined to their bed or home. An In-patient might be (is this a UK word, and not a US word?).

A better clue might be 'without foundation' or 'logically inconsequent'.

+1
Level 37

I didn't get 'The polar ice covering of a planet' as I thought it meant the ice was covering the whole planet or at least was beyond the pole regions.

Ice cap as two words is how the National Snow and Ice Center spell it. I tried ice cap ice sheet...:=(

surprised that more people know incubus than know imperial, implode or ice cap
