Here's a breakdown:
* Lo: This is the object pronoun for "him" or "her" in the singular form.
* amo: This is the present tense of the verb "amar," which means "to love."
* tanto: This is an adverb meaning "so much," emphasizing the intensity of the love.
Note: "Lo" can also refer to "it" in some contexts. However, in this case, the phrase is more commonly used to express romantic love.
