Just based on how often I notice someone mispronounce a word without realizing it (or have done so myself and realized it later). Statistically I’m probably still doing it with some word.
Not exactly related to the question, but as a non-native English speaker, whenever I read something related to weights in imperial, e.g., 150 lbs, my mind reads it as 150 lubes.
I know it’s pounds, if I would read it out loud, I would say pounds cause I’m not a weirdo (well…). But still, my internal monologue has lbs = lubes
