Question: The meaning of Polish 'doing something on knees' or 'on a knee' is completely different than English:  s://www.macmillandictionary.com/dictionary/british/on-your-knees It is rather a metaphor to a student who instead of doing his homework properly at the home, he did it in hurry, supported his notebook on knees and did it in a short break between classes. In other words it means doing something in hurry, usually resulting in poor quality and unsophisticated enough. Some usage: Who designed this building? Looks like some architect 'made it on a knee'... Or nowadays according to software engineering: There are lots of bugs in this application! They came short on deadlines and 'wrote it on their knees' even without unit tests... My question is, is there an English equivalent (in idiom or phrase) which preserves this meaning better? Edit After reading some answers I realized that my examples were a little bit misleading. In reality, the phrase does not carry itself any negative connotations about the 'author'. Rather poor quality of his job results. The only negative connotations about author we can only deduce from the quality of his job: 'He did his job inaccurately so we can assume that he may be inaccurate.' or 'You Will Know Them by Their Fruits' sort of thing.

Question: Is there a single word to describe birds that can fly? Am I struggling to think of a word because the default notion of a bird is that it can fly? So we generally only need to differentiate the ones that can't fly. I've seen the term "winged" in a few google searches, but to my mind an ostrich is winged, but it is also flightless. I guess I'm looking for the word you'd put into this blank: Penguins are flightless because they cannot fly. Ostriches are flightless because they cannot fly. Pigeons are ____ because they can fly. 
Answer: I think you can just use flying to describe them; flying birds sounds perfectly normal and isn't a tautology, nor does it only apply to birds in the air, cf. the title of the Wikipedia article 'Flying and gliding animals'. It's obviously an awkward choice for your example sentence, where another option, volant, could be used instead: 2: flying or capable of flying (source: Merriam-Webster).

yes

Question: Background We have a motivational poster in our office that says: None of us is as smart as all of us. I think that it's grammatically incorrect, and here is my reasoning: All of the tigers have spots. All of us are here. None of us are dead yet. The three examples all sound correct when using the plural "are", rather than "is". Question Unfortunately, some of my coworkers disagree with me. They believe that the quote is correct when it uses the word "is". So my question is this: Is the motivational quote grammatically correct or should it say "all"? 
Answer: "None" is just short for "no one". None is not plural. It's not singular either, but it's even less plural. So "No one of us IS smarter..." I mean, I sure am not, but this is open and shut.

Ex Output:

no
