In a way that is changeable or inconsistent, often showing a lack of loyalty or stability.

Fickly is derived from the adjective "fickle" (from Middle English *fikel*, meaning changeable or unstable), which itself comes from the Old English *ficol* (meaning deceitful or treacherous). The suffix "-ly" (meaning in a manner of) is added to form an adverb. Thus, "fickly" means in a manner that is changeable or unstable.
Think of someone who is 'changeable' ('fickle') in their decisions, and remember that 'fickly' describes doing something in a changeable manner.
