Sentence:  In contemporary Czech, the “hook” or <WSD>caret</WSD> is no longer in use for lower-case "t" and "d" when the latter are palatal; instead, an apostrophe is used ("t''', "d''') This development is clearly connected with the practical difficulty encountered in printing a <WSD>caret</WSD> over letter stems that are too thin. 
Meaning of the word marked with <WSD> tags:  A (háček), ⟨ <big>(ˇ)</big> ⟩.
