sipulta = onion (noun) (some things Google found for "sipulta": a rare term; a rare last name that can be Finnish; similar word silputa means shred in Finnish; similar word sepulta means buried in Latin and buries in Spanish)
Word derivation for "onion" :
Basque = tipula, Finnish = sipuli
Miresua = sipulta
The Basque and the Finnish words for onion are unexpectedly similar, the middle four letters in both words are IPUL. I considered making my Miresua word sipula, but thought that was too like the Finnish word, so I inserted the T from the Basque word to make it slightly different.
This Miresua conlang word has been changed. The word for onion is now tipuli.
