First, I examined pictures taken in Prague.

Example 1

Here, this user wrote the description of her post in Czech but included a large number of anglicisms and English words as well. Interesting is her use of the word swajpu (from the English ‘swipe’), whose spelling she changed to make it conform to Czech phonotactics, and she additionally assigned it the Czech masculine gender and used inflectional morphology to make it into the locative singular case.

Example 2

Here we notice that both the description and the hashtags are exclusively in English, although the user is a native Czech speaker.
