Etymology
The word 'inconstant' is a direct borrowing from Latin inconstans, itself formed from the negative prefix in- and the present participle constans of the verb constare (to stand firm, be consistent). Constare breaks down further into con- (together, completely) and stare (to stand), a verb with a clear Proto-Indo-European root steh₂- (to stand). The literal sense of "not standing firm together" evolved logically into the abstract meanings of changeability and unreliability, describing a person or thing that does not maintain a steady state, position, or loyalty.
