IPA: //rɪˈhoʊbəm//
KK: /rɪˈhoʊbəm/
A large wine bottle that holds the equivalent of six standard bottles of wine, often used for special occasions.
They celebrated their anniversary with a Rehoboam of champagne.
Rehoboam is derived from the Hebrew name "Rehoboam" (רְחַבְעָם), which means "he enlarges the people" or "he who enlarges the people." The name is composed of the root "רָחַב" (rachab) meaning "to enlarge" and "עָם" (am) meaning "people."
Think of someone who 'enlarges' ('rachab') the 'people' ('am') — that's why Rehoboam refers to a figure who increases or expands the community.
