1 “Conflate”, that’s a tough one for this time of day.
2 What’s that word that means that? “Homonym”? I’ll remember after this second mug kicks in.
3 In addition to conflating (I think) homonyms (I think), I also sometimes agglomerate similar-ish words. For example, just now I agglomerated “aggregate” and “conglomerarate” into “agglomerate”. But then I spelled it wrong, and spell-check revealed that it is in fact a word though one whose existence I wasn’t consciously aware of before my accidental rediscovery.
