It's more likely (if we take on the assumption that this is natural language) that the author is not writing in a written language style. It can be hard to appreciate how much spoken language is a literate society is influenced by writing; much of that is due to the fact that we largely keep our memories outside of our skulls these days. Oral language, especially that which is meant to be passed along, is full of repetition, alliteration, rhyme and pun. If the script is something more like an abjad than an alphabet, the repetition may not necessarily be repetition. That may pose additional serious problems if the language (if it is a real language) is an effective isolate (having no documented surviving relatives). An abjad is hard enough to deal with when you have a Semitic-style non-concatenative morphology (words of related meanings have consonants in common, with the vowels changing), but if there is punning without semantically common roots, then all you know is that you have words close to each other that use the same consonants.
