n
A state of proper balance, order, or functioning; good condition.
Etymology
The origin of 'kilter' is obscure, though it is thought to have emerged in the 17th century, possibly related to the now-obsolete word 'kelter' meaning 'good condition' or 'order'. Its exact linguistic lineage is unclear, but it may have connections to Dutch or Low German dialects. The word's journey into standard English reflects a process where a colloquial term for general fitness or proper arrangement gained a more specific, abstract meaning describing a state of balance or correct adjustment. Today, it is most commonly used in the negative phrase 'out of kilter' to describe something that is not functioning correctly or is in disorder.
Analysis
The word 'kilter' is a simplex word of uncertain origin, likely entering English as a dialectal or specialized term. It does not have separable morphemes in modern English.
