1. A body of water, smaller than a river, contained within relatively narrow banks?
Stream. (Canal? Depends on how `relatively' narrow it is.)
3. A metal container to carry a meal in?
Lunchbox, though it's plastic rather than metal, and you may or may not describe its contents as a `meal'.
5. The piece of furniture that seats three people?
Settee, couch, sofa.
7. The covered area outside a house where people sit in the evening?
This question reminds me of the outside bits of the Turf Tavern, which I think are called the gardens even though there's no plants in them; but that's not outside a house unless a `public house' counts. Essentially, if someone from a warmer country described being in the `veranda' I'd probably understand them to mean something like the above, though I'm fairly unlikely ever to use that word in a sentence myself.
8. Carbonated, sweetened, non-alcoholic beverages?
Pop; or their actual description (by brand name, or by saying `fizzy drink'). If in a restaurant I might say `soft drinks'; if the restaurant is in the USA then I might say `soda'.
9. A flat, round breakfast food served with syrup?
If I go to places where such things are served then they are pancakes (because it helps to know what to ask for to get what you want - and yes I often do eat these things in American hotels). Usually, though, a pancake is unsweetened and a lot thinner than an American breakfast pancake.
10. A long sandwich designed to be a whole meal in itself?
A baguette sandwich, or an X baguette (where X is the food item you are planning to put in it - just saying `baguette' sounds like a plain bread stick) - but only if the sandwich is actually made from French(-style) bread. A hotdog (if the thing in the sandwich is a sausage of some description). A sub (because I don't seem to have a default word for long sandwiches that aren't baguettes or hotdogs and I'm influenced by the existence of the `Subway' chain of long-sandwich shops which I've visited on various occasions in the USA).
12. Shoes worn for sports?
When I was young: gym shoes, pumps, plimsolls (only when I felt posh). These days, if I wore such things (which I don't) I'd wear trainers. Last time I was in a sports hall (which is a fair old while ago, and it was for archery(!)) I wore tennis shoes, which are probably pretty similar to trainers. Some sports of course have their own specific footwear, such as footy boots and golf shoes. And tennis shoes, I suppose.
14. A flying insect that glows in the dark?
If I were in an exotic country and happened to see one of these things, I'd probably call it a firefly. I certainly wouldn't call it a glow-worm unless it were on the ground.
19. What's the evening meal?
When I still lived with my parents, we would have `dinner' at midday-ish and `tea' in the evening. Nowadays, owing to the ambiguity of the word `dinner', I'll probably have `lunch' at midday-ish and `tea' in the evening, having skipped dinner altogether. But if it's an evening meal at a restaurant or in a formal setting then it will probably be `dinner'.
20. Passage that runs between two rows of houses?
If it runs between and parallel to two rows of houses, and especially if it's wide enough to fit a car, then it's the back street. Otherwise, it's probably an alley or a ginnel (but not a gnimmel). I haven't used the word `ginnel' in such a long time - I think I may be in danger of forgetting it.
22. Place where pedestrians cross road?
Add `pedestrian crossing' to the list. In fact, a pedestrian crossing is usually a pelican crossing, but it can also denote a zebra, toucan or puffin crossing or any other kind which they have yet to invent and think up a cute bird's name for.
31. Oblate ellipsoid of leaven bread, cut, in two, along its major plane and filled with delicatessen goods?
Sounds like a bread finger or hotdog roll to me, but that really denotes the bread without the filling. No particular word for this, then, but see also Q10.
33. Bumps on surface of skin which appear around pores when human is frightened or angry or cold?
Goose pimples (rarely, goosebumps or goose flesh).
43. That plant that kids throw at each other because it sticks to clothing?
Not something I've ever done - in fact I'm not sure that these grow anywhere particularly near to the house where I grew up. I might call the sticky things `burrs' but that could be hopelessly wrong.
44. Those little balls of froth on plants in spring, which contain some moth or other's eggs?
46. Boys' lower-half underwear?
Pants, underpants, Y-fronts, briefs. Not knickers - those are for girls. Marks and Spencer also sells trunks, but those sound like they're for swimming in.
47. The cloth you had when you were little and always slept with, and perhaps sucked your tongue with?
I didn't, but I understand such things are commonly called security blankets. (Sucking tongue is an entirely different occupation, not really meant for little people.)
48. Warm knitted top typically made of wool?
Jumper or occasionally pullover. But not made of wool because I'm allergic.
49. Baked in an oven, made of flour, butter, an egg, milk:
It sounds like scones, but they'd have to be savoury ones if there's no sugar. I suspect the question is aiming at what the Americans call `biscuits', but such a thing doesn't really exist over here (and a biscuit is of course a thin, sweet, usually hard or crispy baked dough product and definitely not a savoury scone).
50. A single thistledown seed flying free.
A sugar stealer (and why it's called that I have no idea). They also come from rose-bay willow-herb and from dandelions (hence sometimes just called `dandelion fluff').
51. Place where you. Er. You know. Use the euphemism:
Loo, toilet, bathroom.
53. What do you call the paper stuff you use to wipe your nose with?
Hanky, paper handkerchief, tissue.
59. That phone you carry with you?
A phone. Or a mobile, or mobile phone (or phobile moan).
63. Another word for "butt"?
Bum, bottom, botty, arse, rear end, backside, buttocks,. . .
- Q27,28: When I was in the cub scouts I once went canoeing, and the paddle had a blade on each end. I'm given to understand that people within the sport use the term `kayak' when the paddle is double-ended and `canoe' when it is single-ended, but the OED seems to agree that `canoe' can be used as a general term to describe both.
- Q54: A photocopier doesn't actually have a camera inside it!
