Dutch typography regularly seems to use a superfluous colon to introduce a list of items – sometimes even a ‘list’ of one!
The Dutch are great communicators who get their message across well in spoken English. But actually putting the spoken word on paper is a pig with a different snout altogether.
Hold on, that’s the same in all languages… isn’t it?
Separate sentences shouldn’t be glued together with commas, this is poor style.
Open quotes. Someone’s talking. Who? For a while. OK: who? More but from whom? Finally: close quotes at the end of the paragraph and we learn who said it.
