This question already has an answer here:
For example orange - orange describes exactly what it is.
I thought that the word was onomatopoeia but when I looked it up — it's described as sounds; e.g. bleat for lamb or miaow for cat.
I was watching a TV cop programme, and one of the female officers was being unkind/rude about a fellow male officer who was called Dick, saying he was an onomatopoeia. I am sure I did look this up at some point and was given the nicer description of orange as an example of an onomatopoeia. So can someone clarify for me?
