The spelling of the word "diddly" is an interesting case. It is pronounced /ˈdɪdli/ with a short "i" sound, but its spelling features a double letter "d." This is due to the influence of the Irish language, as the word is derived from the Irish word "díolaim," meaning "to deal in." Irish orthography uses double letters to indicate a short preceding vowel sound. Therefore, the spelling of "diddly" maintains this convention, despite being an English word.
Diddly is a colloquial term that has different meanings depending on the context. It can serve as an adjective, a noun, or an adverb. As an adjective, diddly is typically used to express insignificance or worthlessness. For example, one might say "He doesn't know diddly about the subject," implying a lack of knowledge or expertise in a particular field. Similarly, when referring to a small amount or quantity, diddly is employed to emphasize the minimal or unimportant nature of something. An example would be "I didn't do diddly during my vacation," conveying that no noteworthy or significant activities took place.
As a noun, diddly refers to something of little value, significance, or substance. This could include trivial information or details. For instance, "That book was filled with diddly," suggesting that it lacked substance or meaningful content. As an adverb, diddly is used to emphasize that something is being done or achieved in a negligible or minimal manner. For instance, "He barely diddly finished the task on time," highlighting the minimal effort or accomplishment made.
Overall, the term diddly revolves around the concept of insignificance, worthlessness, or a minimalistic nature. It is used to describe things, actions, or qualities that lack importance or substance.
The word "diddly" is believed to be a playful alteration of the word "diddle", which dates back to the early 17th century. "Diddle" initially referred to swindling or cheating someone, but over time, it evolved to mean something trivial, small, or unimportant. The addition of the suffix "-ly" to "diddle" created "diddly", turning it into an adverb/adjective form. This alteration also adds a touch of whimsy or childishness to the word. It gained popularity in the mid-20th century, particularly through its usage in phrases like "diddly-squat" or "diddly-poo", often used to emphasize the insignificance or worthlessness of something.
