English speaking foreigners to the Czech Republic who are interested in the
language are often befuddled or even annoyed by the feature of formal and
informal speech in Czech grammar, called vykání and tykání - that is,
the formal, plural “you” and the informal, singular “you”. Nowhere
is that characteristic more frowned upon than in multinational companies,
where new employees, called “formal you” at the job interview, are
renamed “demotic you” on their first day of work, and told to address
everyone else accordingly.
