Maftir
Maftir (Hebrew: מפטיר, "concluder") refers to the last person called up to the Torah on Shabbat and holiday mornings: this person also reads the haftarah portion from a related section of the Nevi'im (prophetic books).
Informally the portion of the Torah read by or to the maftir is called the "maftir portion", or the "maftir" for short: in a Chumash the word "maftir" is printed in the margin at the beginning of that portion. (Accordingly, in those communities where the bar mitzvah acts as maftir, his readings are informally referred to as "maf and haf".)
