I always enjoy getting emails from the Oxford English Dictionary folks about revisions to that massive work. This month’s updates are no exception.
In origin a representation in print of a regional or colloquial pronunciation of anyhow, this new entry retains the core senses of that word. In more recent use, however, especially in North America, it has gained a specificity which earns it separate coverage from its “parent” in the OED, in use to indicate a change of subject in a conversation, sometimes as a very deliberate or ostentatious marker that the current subject has become too convoluted, dull, or indecent for talk of it to continue.
Cool. I love language.
