IELTS vocabulary: War and Conflict

War and conflict appears on the test more often than candidates expect: Task 2 prompts about whether international bodies should intervene in other countries' conflicts, Part 3 discussions following a Part 2 cue card about news, history, or a country you'd like to visit, and occasionally General Training material referencing a conflict's humanitarian impact. The specific difficulty with this topic isn't a lack of vocabulary — most candidates can say "war is bad" and "people suffer" without hesitation — it's that those phrases are too generic to build an actual argument on, and too imprecise to discuss the topic with the seriousness it requires. An essay that only ever says "war" and "conflict" interchangeably, without naming a cause, a specific consequence, or a specific response, reads as though the candidate hasn't thought carefully about a topic that deserves careful thought. This article works through the vocabulary an actual answer needs — causes, consequences, response, and aftermath — with attention throughout to using it with appropriate seriousness rather than as a checklist.

Vocabulary for causes lets an essay move past the flat claim that conflict simply "happens." "Armed conflict" is the general term for organised violence between states, groups, or factions, distinct from "civil war," which specifically means armed conflict between organised groups within a single country rather than between separate states. "Territorial dispute" names disagreement over control of land or borders, one of the most common underlying triggers of interstate conflict, while "ethnic tension" and "political tension" name two distinct categories of internal division that can escalate into conflict without necessarily involving territory at all. "Insurgency" refers to an organised rebellion against an established authority or government, typically using irregular tactics rather than conventional battlefield warfare — a term worth distinguishing from a full civil war, since an insurgency can occur without the broader population or state institutions being formally divided into two warring sides. "Proxy war" describes a conflict in which larger powers support opposing sides without direct military engagement themselves, a mechanism worth naming specifically in essays discussing why some conflicts persist longer or involve more external actors than their local origins would suggest.

Vocabulary for consequences splits usefully into human and material impact, and most weak essays only ever gesture at the first without any precision. "Civilian casualties" refers to deaths and injuries among the non-combatant population, a term that should be used carefully and precisely rather than as filler. "Forced displacement" describes people being compelled to leave their homes because of conflict, and it's worth knowing the more specific terms beneath it: a "refugee" is someone who has crossed an international border to escape conflict or persecution, while an "internally displaced person" (IDP) has been forced from their home but remains within their own country's borders — a distinction that matters because the two groups face different legal protections and different humanitarian response mechanisms. "Infrastructure destruction" covers damage to the physical systems — housing, hospitals, roads, water supply — that a population depends on, and is worth naming specifically rather than folding into a vague reference to "damage." "Economic collapse" and "food insecurity" name two of the most consequential downstream effects of prolonged conflict, frequently outlasting the fighting itself by years.
