The word inconsistent comes from the Latin in- (meaning 'not') and consistere (meaning 'to stand together'). Literally, it describes something that cannot 'stand together' because the parts are fighting each other.
It entered English in the 17th century. During that time, it was often used in philosophical debates about logic. If your argument was inconsistent, it meant your points contradicted one another. Over time, the word moved from strict logic into our daily lives to describe everything from weather patterns to human habits.

Inconsistent is an adjective. To make it a noun, we use inconsistency. The adverb form is inconsistently. It is pronounced /ˌɪnkənˈsɪstənt/ with the stress on the second syllable.
It rhymes with words like persistent and resistant. Notice how the prefix 'in-' creates the negative meaning, which is a very common pattern in English grammar for creating opposites.
