The word "diddler" is derived from the verb "diddle", which means to fool, swindle, or cheat, especially by deceitful or fraudulent means. The origins of "diddle" are somewhat unclear, but it is believed to have emerged in the late 18th century or early 19th century. One theory suggests that it could be a variant of "duddle", which means to lead astray or deceive. Another possibility is that it comes from the word "dodder", meaning to totter or shake unsteadily, implying the shaky or unsteady nature of deceitful actions. Over time, the term "diddler" evolved to refer to a person who engages in trickery, fraud, or deception.
