title_body: What to do when my conlang has a word that means something in one of my languages?
upvoted_answer: These sorts of coincidences are somewhat inevitable. Just try to accept that there's a limited number of ways to arrange sounds in your language, and some will sound similar to words in other languages.
  
  When I was trying to learn Hungarian, I came across a number of words that reminded me of words I knew in English and other languages. Some examples:
  
  
   repülőter "airport" /  re-polluter
   csillag"star" /  ceiling
   és "and" /  es "it is"
   a nap "the sun" /  a nap
   a bolt "the store" /  a bolt
   öt "five" /  otto "eight"
  
  
  I also had a recent case on the CBB where I posted my conlang Atili's word for "citrus" zilu, and immediately got asked if I borrowed that word from Kankonian (another conlang) tzelua "citrus." I hadn't. CBB thread
  
  Then there is the fairly well-known case of the Mandarin filler phrase 那個 / 那个 nèige, which sounds to many English speakers like a racial slur. See this posting on the Chinese language stack for more details: Very frequently used word in Mandarin that sounds like "nica" or "nigah"
