Here's a breakdown:
* Semper means "always" in Latin.
* Fidelis means "faithful" in Latin.
Therefore, "semper fidelis" means "always faithful".
"Lagging lagi" directly translates to "always faithful" in Tagalog.
However, depending on the context, other Tagalog translations might be more suitable, such as:
* Tapat magpakailanman (faithful forever)
* Matapat sa lahat ng panahon (faithful in all times)
The best translation will depend on the specific context in which the phrase is used.
