What is the meaning of lo
What do lo really mean do it mean what or it?
This article also mentions its use in the loísmo and to refer to preceding nouns or adjectives with ser and estar.
¿Es nueva tu computadora?. No lo es. "Is your computer new?" "It isn't."
¿Estaban felices?. Sí, lo están. "Were they happy?" "Yes they were."
I usually translate it as "the thing"
Lo importante es - the important thing is
Lo que - the thing that
Lo de - the thing about

LO can mean it, him, her, and you. LO can also mean "the."
"The thing" is also a good translation in many cases as patch said.
