What does inconstant mean?
Inconstant describes something that changes frequently, unpredictably, or without consistency. The word can refer to physical conditions, such as inconstant weather, or to human character, such as inconstant loyalties or attention. It implies not merely that change occurs, but that the subject is difficult to rely on because its qualities do not remain stable. The term is somewhat literary and formal, and it often conveys a sense of unreliability or instability. Incontrast to a steady or constant quality, an inconstant one is liable to fluctuate. Related forms include the noun 'inconstancy' and the adverb 'inconstantly'.

Where does inconstant come from?
The word comes through French from Latin 'inconstans', formed from the prefix 'in-' meaning 'not' and 'constans', meaning 'steady' or 'constant'. Latin 'constans' itself was based on 'constare', 'to stand firm'. The resulting English adjective has been used since the early 16th century, and related forms include 'inconstancy' and 'inconstantly'.
