Poglish

Poglish, Polglish or Ponglish (in Polish, often rendered "Polglisz"), a portmanteau word combining the words "Polish" and "English," designates the product of macaronically mixing Polish- and English-language elements (morphemes, words, grammatical structures, syntactic elements, idioms, etc.) within a single speech production, or the use of "false friends" and of cognate words in senses that have diverged from those of the common etymological root.
