Folk or popular etymology is one unusual example of such a change. Language borrowings, another type of analogy, occur when the speaker of one language adopts foreign words into his own lexicon, making them conform to his own linguistic patterns. Folk etymologies and borrowing can occur in many different ways. Folk etymology is a particular type of misanalysis in which a word or part of a word is modified in terms of familiar or accessible words or morphemes.
Folk etymologies occur in many Romance languages as well as in English.
We observe that the sound of the words sam and sand were similiar, and one can be blinded from sand. The phonetic similarity of these two items made the analogy possible. Likewise, the change from garter snake to garden snake is phonetically plausible. The two words look similar, and garter snakes are found in and near gardens. Moreover, we associate garters with round elastic hose, not a longitudinal stripe.
