Manong (Mah-noh-ng) is an Ilokano term principally given to the first-born male in a Filipino nuclear family.
It is a term of respect, similar but secondary to Dad or Mom, but not comparable to Mister or Ma'am, which expresses no elevated affection.
Additionally, the male partner of an older sibling may be referred to as a manong irrespective of the speaker's age relative to the partner (i.e., a male younger than the speaker may be called manong by virtue of status and not by age difference) although this is not always necessary.
Stories of the manong, Filipino migrants displaced from their homeland and faced with the racism and challenges of a foreign land, is a common theme in many Filipino-American writers' works.
These include most prominently, Carlos Bulosan (America Is in the Heart), a Filipino migrant himself, and several stories by Bienvenido Santos "Scent of Apples" and "The Day the Dancers Came").
