"Onion" and "salsa" possess a similar structure: both words consist of two identical 2-letter syllables and a distinct letter between them.
Apparently, there are more English words of similar form (12312).
Find as many as you can.

I agree about polymorphous obfuscation!  One can always save up new vocabulary for rainy days.  By-by (oops!).
