I leave you a list of words with umlauts, such as penguin, ambiguity, shameless, flattering, linguistic, multilingual or stork. The umlaut is a linguistic sign that is formed by two points ¨ that are written horizontally, on the affected vowel.
In the Spanish language, the umlaut is used placed on the vowel «u», when it is pronounced when forming the syllables «gue» or «gui». As in the case of the word penguin or ambiguity.
