As a general rule QUESTION MARKER “BA” will precede a personal pronoun
Amerikano ba ko – Am I an American?
Amerikano ka ba – Are you an American? (note the placement of ba)
Amerikano ba siya – Is he an American?
Amerikano ba kita – Are we American? (inclusive of who you are talking to)
Americaon ba kami – Are we American? (exclusive of who you are talking to)
Amerikano ba kamo – Are you all American?
Amerikano ba sila – Are they American?
The “BA” precedes the personal pronouns except for “you”
Amerikano ba ka sounds very bad to Filipino ears.
Compared to English Cebuano has very few such exceptions.
