Concept:ECOWAS focuses on economic cooperation and integration, not cultural or linguistic unification.
Explanation:ECOWAS was formed to promote economic development, cooperation, and regional integration among West African states.
Its main objectives include improving trade among member countries, encouraging the free movement of people, goods, and services, and developing infrastructural facilities such as roads, railways, and communication networks.
However, unifying the different languages spoken by member states is not an objective of ECOWAS.

No single language can be imposed as a common language because all member nations are equal and independent.
Therefore, promoting a common language is outside the scope of ECOWAS.
