Spinney is a nice word for a smallish gathering of trees, alongside copse, coppice, etc. I’m not aware of a term for one specifically in an open field, though.

Apart from the hole, that could be chicken on a raft, an old Royal Navy dish.

I haven’t tried it myself yet, but you can get yeast improvers , a powdered ‘mother yeast’ that claims similar results to sourdough.

I have a starter in the fridge that I only use once every two or three weeks, and have not had any mould problems; perhaps you just have to be only a little less lazy to keep a viable one, and feed on that sort of a schedule?

I agree though, that making sourdough bread can be a nuisance time-management-wise until you find some sort of rhythm that suits you.

I can’t go on. I’ll go on.

I don’t think I’ve come across that before, but I’d say it depends on what is meant:

• I don’t know what that thing is.
• There is a thing, but I don’t know what it is.
• There is a thing such that I don’t know what it is. I.e., I do not know what all things are.

There may well be some other ones, but I don’t know what they might be.

I have a Xerox colour laser printer that I’m very happy with: accepts off-brand toner, speaks postscript, good quality printing, no problems at all. I’ve also been very happy with Brother laser printers in the past.

Oddities and Curiosities of Words and Literature by C C Bombaugh, one of my favourite reads, feels like it might be an obscure book.
