Trello means crazy in greek.

[torstein]

And 'trell' means slave in norwegian.

I don't think you can avoid this kind of thing if you want a short and pronounceable name.

I think you mean "τρελός" :)

From the look of it, there's only one L.

Actually, it used to be spelled with a double "λ" but went out of fashion in favor of the simpler form.

[zerostar07]

There's an older spelling with double lambda. Also, trello is the neuter gender.

[pagekalisedown]

Sounds a bit like "traineau" in french, which means "sleigh".
