What does coalitionism mean?
Coalitionism is the doctrine or practice of pursuing political goals through coalitions — formal or informal alliances between separate parties, factions, or interest groups. The term appears most often in discussions of parliamentary systems where no single party commands a majority, making coalition-building essential to forming a government. In such contexts, coalitionism describes not merely an occasional tactic but a governing philosophy: a commitment to negotiation, compromise, and shared power rather than unilateral action. The word carries a dual connotation. To supporters, it signals pragmatism, inclusiveness, and democratic maturity; to detractors, it can imply opportunism or an absence of firm conviction, since coalition partners may abandon principles for the sake of agreement. Though rare in casual conversation, coalitionism is a useful analytical term in political science and journalism, capturing the difference between systems built on majority rule and those built on negotiated consensus among allies.
nounThe practice, policy, or advocacy of forming or governing through coalitions — temporary alliances between distinct parties, groups, or factions pursued for common advantage.
- The political practice or strategy of building and maintaining coalitions among parties or groups to attain or exercise power.
- A general disposition or ideology favouring cooperative alliance over independent or unilateral action.
"Critics accused the party of embracing coalitionism only when it suited its electoral fortunes."
"In proportional-representation systems, coalitionism is less a tactic than a way of governing."
"Her lifelong commitment to coalitionism made her a bridge-builder across otherwise rival movements."
Rarely pluralized; the plural would appear only when contrasting different doctrines or traditions of coalition-building across contexts.
"Comparing European and Indian coalitionisms reveals very different assumptions about power-sharing."
Behind most governments that no single party can control lies an unwritten creed — coalitionism — that says sharing power beats losing it entirely.

Where does coalitionism come from?
Coalitionism is formed by adding the suffix '-ism' to 'coalition', which entered English in the early 17th century from French 'coalition', ultimately from Latin 'coalitus', past participle of 'coalescere' ('to grow together'), itself from 'co-' ('together') plus 'alescere' ('to grow up'), a derivative of 'alere' ('to nourish'). The suffix '-ism' converts the concrete practice into an abstract doctrine or ideology. Cognates sharing the same Latin root include 'coalesce' and 'coalition' itself.
