What is 'Eu sou louco por você' when translated from Portuguese to English?

"I'm crazy about you!" is an English equivalent of the Portuguese phrase Eu sou louco por você!

Specifically, the subject pronoun eu -- which does not have to be used other than for emphasis in this case -- is "I." The present indicative verb sou means "(I) am." The masculine adjective louco means "crazy, mad." The preposition por means "for, through." The personal pronoun você translates as "(informal singular) you."

The pronunciation will be "EY-oo so LO-koo poor vo-SEY" in Carioca Brazilian and continental Portuguese.
