Lynguistykon: Loanword
From The Somewhere Else Encyclopedia
A loanword is a word imported from one language to another for relatively regular use in it. This is especially common when a phenomena is primarily or originally observed by a certain people group and then later known to others.
Popular Language words, especially Peoplespeak ones, are often used alongside words by a speaker in their native language, but while some may view these as loanwords others may simply view them as Popular Language/Peoplespeak words used in conjunction with other languages.
