coalitional

The adjective 'coalitional' is built directly upon the noun 'coalition'. The noun itself originates from the Latin verb 'coalescere', meaning 'to grow together' or 'to unite', which is a compound of 'co-' (together) and 'alescere' (to grow up, increase). This etymological sense of disparate elements growing into a unified whole perfectly captures the modern political and social meaning of a temporary alliance between distinct groups. The suffix '-al' is then appended, following a standard pattern in English for forming adjectives from nouns, to create a term that describes anything pertaining to such an alliance.

Structure: coalition (coalition) + al (adjective suffix) coalition (from Latin 'coalitio', meaning 'a growing together, union'); al (from Latin '-alis', an adjectival suffix meaning 'of, relating to').
