Can you give some examples?
A few maybe ...
My latest "aversion" is the letter combination "mid" when it is applied as a prefix ... midday, midnight, mid-anything, even middle, stops me in my tracks and I have to struggle to find or get back to context. Mid is very descriptive. It overwhelms my perceptions. I used to date a girl from Midland - maybe that's my problem.
This happens with many prefixes. Ante- and anti- and pan- and con- and uni- are also picture hungry. A few suffixes hit me, too, like -le and -age. "Out" is no problem, but "outage" is a stumbler. "Handle" is a word that creates so much anxiety in my mind that it is difficult to move away from, because of the blast of imagery, but I have finally figured out that it is the -le on the end. I am captured by its power. Don't worry -ed is easy. Many other -le suffixes are almost as bad. It is like they are TOO flexible and have too many uses.
Combining suffixes is also rough, like the word manageable, which comes from Latin for "hand" plus the two suffixes. That's only one example of multiple
fixing of words, but it is a very sticky one, to me. Of course many words are common prefixes added to common suffixes, like multiple, but they don't get to me as much for some reason.
A few simple words that cause me delays (all convey too many meanings) ... gone, able, flux, though, carry, gain, drop ... many more, too.
I use all these words, but they can take extra time if I hear them in conversation.
I'm not sure what you're looking for, but this delay in processing thing is something that I have given a lot of thought to in recent years.
I await my analysis.
