1o_ La 'y' (ye , colloquially called "i Griega") is the twenty-sixth letter of the Spanish alphabet, inherited from Latin, which incorporated it around the first century to be able to write words of Greek origin, since it is based on the Upsilon; ( capital issil) . It has value as vocal (pronounced as 'i latina') and also as consonant (pronounced similar to 'll'). 2o_ In Spanish it has been used since 1726 as a connector or copulative conjunction, sometimes replaced by 'e' when the next word begins with loud 'i' sound.
