I was trying to determine about how many words there are in English, with four letters. (Ideally, excluding "s" plural, so cats and dogs would not be included.)
Does anyone have any concrete information on this such as an academic paper or perhaps some info from a dictionary or other reference I am unaware of?
(My investigation produced a number - I won't state it - which seemed wrong.)
Many fascinating related questions have come to mind: for example, "What's the most popular length of word in English?" (You'd think we'd all intuitively know this as native speakers; I don't.)
