How can this sentence have a negative meaning without a "no"?

Question

How should I translate this sentence? > En mi vida le he visto This sentence has the same meaning as `No le he visto en mi vida`, which means I haven't seen him in my life. But there is not a negative 'no' in the sentence `En mi vida le he visto`. Why the sentence express the negative meaning?

Answer 1

"En mi vida le he visto." Translates to "In my life I have seen him".

If you'd want to say that phrase in Spanish as "I haven't seen him in my life" without "NO", you could use the word "nunca" which means never.

"Nunca en mi vida le he visto."

Does this help?
