Here are some examples:
* "Nasaksihan ko ang aksidente." (I witnessed the accident.)
* "Siya ang nasaksihan sa kasal." (He was the witness at the wedding.)
* "Naghahanap sila ng mga nasaksihan sa krimen." (They are looking for witnesses to the crime.)
"Nasaksihan" literally translates to "being witnessed" but the most natural English translation is simply "witness".
