* Yo: The Spanish word for "I"
* estoy: The present tense form of "estar" (to be)
* enamorado: The masculine singular form of "enamorado/a," meaning "in love."
Origin:
* Yo: This pronoun has roots in the Proto-Indo-European language, which is the ancestor of many European languages.
* Estar: This verb is also of Proto-Indo-European origin. It's related to the English verb "to stand" and has evolved over time to signify "to be" in a state or condition.
* Enamorado: This word is a compound of "en" (in) and "amor" (love). "Amor" comes from the Latin word "amor," meaning love.
In summary:
While the individual words have long histories, the phrase "yo estoy enamorado" is a fairly modern construction in Spanish, simply combining these elements to express the concept of being in love.
