Pronunciation: [bˈaksla͡ɪdə] (IPA) 
The word "backslider" is spelled with the letter combination "cksl" in the middle, which may seem unusual. However, this is because the letter "c" represents the sound /k/ and "k" represents /k/ as well, but "c" is used before "k" and "e" as in this case. The word is pronounced /ˈbækˌslaɪdər/, with stress on the first syllable. It refers to someone who reverts to bad habits or beliefs after previously improving or reforming.
A backslider is an individual who regresses or reverts back to previous behaviors, beliefs, or practices that they had previously renounced or abandoned. The term is often used in a moral or religious context to describe someone who falls back into sinful or immoral behavior after previously committing to a more virtuous lifestyle.
In religious contexts, a backslider is often viewed as someone who has turned away from their faith or has abandoned their religious commitments. It suggests a deliberate rejection or denial of the principles and teachings that were once embraced by the individual. They may have initially shown commitment to their faith or religious beliefs but have since become complacent, negligent, or indifferent, thereby compromising their relationship with the divine.
The term backslider can also be applied in broader contexts outside of religion. In a more general sense, it refers to anyone who exhibits a decline or setback in their progress or growth. This could be in relation to personal development, moral conduct, or professional accomplishments. Backsliding implies a loss of discipline, motivation, or enthusiastic pursuit of goals.
Overall, a backslider is characterized by their failure to maintain or adhere to a once-held standard of behavior or belief. They represent a departure from positive or virtuous practices, often resulting in setbacks, disappointment, or dissatisfaction.
One who falls from religion and the practice of virtue.

The word "backslider" originated in the 16th century in Middle English. It is derived from the combination of two words: "back" and "slide".
The term "back" originated from Old English "bæc", which referred to the rear side or the opposite direction. It is related to other Germanic languages such as Old High German "bah" and Old Norse "bak".
The word "slide" originated from Middle English "sliden", which came from Old English "slīdan". It means to move smoothly along a surface or to move without control. The root of "slide" is also seen in other Germanic languages such as Old High German "slītan" and Old Norse "slíðr".
Therefore, when combined, "backslider" refers to someone who moves backward from a previously held position, especially in a moral or religious sense.
