IPA: /ɪnˈkɒnstəntli/
KK: /ɪnˈkɒnstəntli/
In a way that is not consistent or stable; changing frequently.
She inconstantly changes her mind about what to eat for dinner.
Inconstantly → It is formed from "in-" (meaning not) and "constans" (from Latin, meaning standing firm or stable) and the suffix "-ly" (meaning in a manner of). The word "inconstantly" means not in a manner of being firm or stable, indicating a lack of consistency.
Think of 'not' ('in-') being 'stable' ('constans') — that's why inconstantly means not stable or consistent.
