This verb combines 'hyper-' (beyond) with 'think' to mean thinking of oneself beyond what is appropriate—being conceited or arrogant. In Romans 12:3, Paul warns believers not to 'think more highly of themselves than they ought to think' but to think with sober judgment. The play on words in Greek (using multiple forms of 'think') emphasizes right self-assessment versus inflated self-opinion. Translations consistently capture the vice of excessive self-regard.
