Guerrilla

noun; also attributive/adjective (as in "guerrilla warfare", "guerrilla tactics")
/ɡəˈrɪlə/
A form of irregular warfare in which small, mobile groups of fighters use hit-and-run tactics — ambushes, raids, and rapid retreats — against a larger conventional army, as perfected by Shivaji in the Western Ghats.

✍️ Usage in a UPSC answer

In counter-insurgency operations, the state's dilemma is acute: heavy-handed force against guerrillas who melt into the local population often alienates that very population, whereas a "hearts and minds" approach addressing grievances of governance and development tends to drain the insurgency of its social base.

🌱 Word Family

guerrilla (adj, attributive), guerrilla warfare (n phrase), guerrillero (n, Spanish)

🔡 Root

Spanish guerrilla = little war (diminutive); guerra = war; from Germanic werra = strife

📜 Etymology

From Spanish guerrilla, a diminutive of guerra ("war"), itself from Germanic werra ("strife"); the term entered English in the early 19th century during the Peninsular War against Napoleon.

🧠 Memory Hook

"Little war" — Spanish guerra (war) + the diminutive -illa. Picture a lone fighter ambushing from the jungle, easily confused with a "gorilla" (same sound) swinging out to strike — a small force waging a small, scrappy war.

🎯 How This Word Works in UPSC Writing

Irregular warfare conducted by small mobile forces against a larger conventional army. Shivaji's campaigns are the standard Indian illustration, and the method should be explained through its conditions rather than as mere daring. The broken terrain of the Western Ghats denied a large army room to deploy and made supply lines long and vulnerable; light Maratha cavalry travelled without heavy baggage and could disperse and reassemble; and a network of hill forts provided secure bases that an enemy had to reduce one by one at ruinous cost. Ganimi kava, the Marathi term for the method, therefore rested on geography, mobility and fortification working together. The strategic insight worth carrying into modern answers is that guerrilla warfare aims not to defeat an army in the field but to make occupation more expensive than withdrawal, which is why it is the recourse of the weaker side and why counter-insurgency turns on separating the fighters from the population that sustains them.

⚖️ Don’t Confuse It With

Guerrilla warfare uses small mobile units and avoids pitched battle, whereas conventional warfare seeks decisive engagement between massed forces. Ganimi kava is the Marathi term for the Maratha practice of it. An insurgency is an armed movement against an established authority, of which guerrilla tactics are the usual method rather than a synonym. Counter-insurgency is the response, and its central problem is that force applied against fighters embedded in a population tends to alienate that population.
