Loanword

A loanword is a word taken from another language with little or no modification. The pronunciation is always modified, because it must use phonemes in the receiving language.

English has been an enthusiastic borrower of words from other languages, although with its rise as an international language the tide seems to be running in the other direction. Some countries take steps to protect their languages from "contamination" by English words whilst others seem more relaxed.
