means A minor, often procedural detail that changes the outcome of a situation even though the bigger picture argues otherwise.

from Traces to 'technical,' from Greek 'tekhnikos' meaning pertaining to art or craft, rooted in 'tekhne' (skill, craft). The word narrowed over time into the sense of specialized, rule-bound expertise — think the fine print of a craft or trade. 'Technicality' emerged as the noun for a minor point within that specialized system, especially a legal or procedural one. It's the same root that gives us 'technique' and 'technology' — all descended from the simple idea of knowing a craft's inner rules well enough to exploit its tiny seams.
