in‧na‧mo‧rà‧re

Italian

1.  to fall in love

2.  to enchant, charm, fascinate

Etymology

From Latin "in" + amore "love," from Latin amor

"In-" Word-forming element meaning "in; into."

The Latin 'in-' became 'en-' in French, Spanish, Portuguese, giving us the French énamourer, Catalan enamorar, Portuguese enamorar and Spanish enamorar, but remained 'in-' in Italian. 

"Amore" From the Greek verb mao – to desire – derived the Latin word amor. 

The word “amare” is a verb. It means “to love.” The related noun “love” is “amor”.
