According to dictionaries, the noun ilk does not necessarily have negative connotations. Derived from a Scottish term meaning the same, the word is synonymous with type and kind, and it’s usually used in phrases like of that ilk or of his/her ilk. It refers to a person’s associates or colleagues. Logically, there’s nothing inherently disparaging about this sense of ilk. It’s neutral.
But in contemporary usage, ilk has become negative. This is perhaps due to ilk‘s similarity in sound to negative words like ill and ick. The connotations are often subtle, but often when someone refers to a person along with his or her ilk, it is meant in a disparaging or dismissive manner.
Of course, we are still free to use ilk in its undisparaging sense, but this is becoming increasingly difficult due to the word’s growing negative associations. When you attempt to use it in a neutral way, you risk giving readers the wrong impression of how you feel toward the people you’re talking about.
