And it’s ‘post-truth’.
Like previous words of the year, it reflects our changing society.
Winners in the past have included ‘selfie’, ‘simples’ and ‘bovvered’.
But while these past winners seem to be more social and upbeat, ‘post-truth’ is different.
And when you look at the other words on the shortlist, it tells us a bit more about how the world looks in 2016.
There was ‘adulting’ (behaving like a responsible adult), ‘chatbot’ (a computer designed to communicate like a human) and ‘hygge’ (a Danish concept of cosiness and wellbeing).
All in line with previous years.
But others on the shortlist included ‘alt-right’ (extreme conservative views), ‘Brexiteer’ (I shouldn’t need to explain) and ‘woke’ (being alert to injustice, particularly racism).
There was even ‘coulrophobia’ – an extreme or irrational fear of clowns.
So, what do these choices tell us about today’s world?
For many, the rise of the alt-right in the US, the Brexit vote in the UK and even the need to become more alert to racism show the world is a more dangerous place.
And as for a fear of clowns, the spate of clown attacks around the world just heightens that sense of danger.
But, for me, ‘post-truth’ is the most dangerous concept of all.
The dictionaries define it as “relating to or denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.”
In short, the truth matters less than it did.
If you feel something is true (or false), then it doesn’t matter whether it is or not.
Even if all the evidence is stacked against you.
Which could have major implications.
In fact, it could make things a lot easier for copywriters like me.
In the past we had to justify any claims we made in adverts or marketing materials.
Even when we were appealing to the audience’s emotions.
Now, as long as the audience believes what we tell them, can we say anything?
Some might think so.
And they might start to test the theory.
So, you might ask, what harm would it do if occasionally we let our emotions get in the way of the truth?
After all, there have been plenty of examples of advertisers who did just that, by appealing to what consumers wanted to believe.
And, yes, when you’re talking about yoghurt or breakfast cereals it might seem trivial.
But what about pharmaceuticals?
Because when politicians routinely resort to blatant lies and appeal to emotions over facts, then it becomes increasingly dangerous.
And that’s not just ‘post-truth’.
It may well be post-everything.
