Let me double check

CERTAINLY, IF YOU MUST. But perhaps you could check first, and then double check only if you really need to do so?

It’s part of a proliferation of extraneous words that serve no purpose other than to make sentences longer. Why should we pre-book when previously we’d just book?

These extra words are particularly popular in restaurant menus, where they make dishes sound more carefully prepared. We’re offered plaice that is pan-fried, chicken that is oven-roasted, and ham that is hand-carved. It’s nonsense, and everyone knows it.
