Each year the Oxford Dictionary combs through the language as it was used that year to select a word of the year. The team of experts that make this choice contains some lexicographers, consultants, the dictionary’s marketing team and their editorial staff. Since the Oxford dictionaries have both a US and a UK version they will each pick a word of the year. Sometimes they will both select the same word and other times each will have their own choice. This year they have both selected “post-truth”, which is when objective facts are less important than pleas to emotions.
