Synecdoche is a word I’d never come across until I opened the dictionary at random just now. Despite never having heard of this device previously, I have used it. I wouldn’t be surprised if you have too. A synecdoche is a figure of speech in which part of something represents the whole.
For example you might refer to a traditional Sunday lunch as ‘a roast’ even though the vegetables and gravy were cooked in another way. It’s generally understood that ‘a blonde’ will have more body parts than just her hair. When we refer to writing a book we generally also mean planning, rewriting, editing, proofreading and trying to find a market, not just bashing out a first draft.
Here’s a picture of a couple of birds – which, I think, is a synecdoche for a picture of a couple of birds and their shadows and a dead leaf, on some grass which has been marked to form a football pitch.

Keep is a good word (not least because it gives me another chance to post a photo of a castle – do you know which one?)
It means to continue to have something, to save something for future use, store in a regular place (we keep The Sphere in the garage), continue in a particular position or activity (she kept her head down) or to remain in good condition (fresh bread doesn’t keep very long). It can also mean to do something you promised to do (I keep my promises) to provide accommodation and food – or the money for those things (he earns his keep)
If you have a friend with enough money you could be a kept woman. You might want to keep up to date, or with the Jones’. Or perhaps you’ll attend keep fit classes (which generally means get slightly less unfit rather to maintain an existing state of fitness in my experience) and of course it’s the strongest part of a castle.
Not bad for just four letters, eh?
I do have a brother, but this post isn’t about him. It’s about
