Etymology
The word "guerilla" entered English from the Spanish "guerrilla," meaning "little war." This Spanish term is itself a diminutive of "guerra" (war), which originates from the Germanic "werra" (meaning strife, confusion, or quarrel), likely introduced into the Iberian Romance languages during the early medieval period. The modern English meaning crystallized during the Peninsular War (1808–1814), when Spanish and Portuguese irregulars effectively harassed Napoleon's forces. Thus, the term's journey reflects a shift from a general term for a small-scale conflict to the specific concept of irregular, non-state combatants who wage such a war.
Analysis
The entire word "guerilla" is a loanword from Spanish. It is a diminutive form of "guerra," meaning "war." The "-illa" suffix is a Spanish diminutive ending.
