Harambee is a Swahili word meaning 'all pull together,' and it is the unofficial motto of Kenya — embedded in the national coat of arms. Historically it named the practice of villages mobilising to build schools, clinics, and roads through pooled labour and money. Today it survives in everything from project management to fundraising to family decision-making. It is a complete grammar for collective effort.
