Please help me about English Expression.

"Web savvy" (s a v v y) means "knowledgeable about the web/internet." "Savvy" is a word adopted from the French "saber" (to know).
It refers to practical knowledge. Someone who is web savvy, is an expert in the use of the web because of their experience working with it.

Thank you so much.

Sorry, you are partially correct. I misread the dictionary entry since the editors use "fr" as an abbreviation for both "French" and "from." However, the dictionary entry does not cite a Spanish source, but traces "savvy" to the Portuguese "sabe" (he knows), a form of the verb "saber" (to know). Spanish has the same verb as the Portuguese, but is not the English source of the word savvy.

It depends which dictionary you consult Several say that the verb comes from the Spanish or Portugese 'saber'; interestingly they say that the noun comes from the French 'savez-vous?'
