As it’s Sunday morning, I decided to have a moan about this ridiculous malarkey.
The phrase “always had trouble”, is perfect English, and I always have trouble with LT wanting me to change the word order.
Ok, I don’t actually have trouble with it as I ignore it.
So if someone can tell me why “had always trouble” is correct, I’ll be surprised. Just because “always” is an adjective, doesn’t mean that it’s going to follow adjectival rules in this instance.
