'Equilibrium' is the correct spelling, referring to a state of balance or equal distribution among opposing forces. The word derives from Latin 'aequilibrium' combining 'aequus' (equal) and 'libra' (balance/scale). The common misspellings in other options result from phonetic errors and misplaced vowels. The word is used in physics, chemistry, economics, and everyday contexts to describe balanced states where opposing influences cancel out.
