There's also the things which might be termed "gimsu" - they are the same except with a medial consonant pair reversed. Consider sodva/sovda. That confuses me every time.

  • ratcu ractu - cfipu sai mu'i lenu roreri mabru

  • and xrula, xlura
    • the bugger with this one is that you think 'flora' and that yields a falsefriend with xlura. --And
    • you mean xruli? --tsali
      • I doubt it, since that word's not in my gismu list, but xrula is ("flower"). mi'e filip.

(Some of us (me anyway) have been wondering about punning in Lojban,
& these last two types seem extremely promising...anybody want to
write some jokes?)

One that's come up so far is ko ko kruji "turn yourself into cream" as a pun on ko ko kurji "take care of yourself" — turning a popular(?) expression of goodwill into an insult or a threat. mi'e filip.
