It seems an all too remarkable coincidence that Nautica, who apparently has never been to "Eart," has somehow come across a derivative of the Latin word for sailor (
nauticus), in the form that English uses it in the superlative inflection of "nautical," then coincidentally decides that she doesn't like the name ending with a lateral consonant and decides to remove it, thus reverting the word back to its original Latin feminine nominative & vocative case of
nautica (or possibly ablative if she stresses the final vowel).
Really? She's managed to learn
that much about Earth languages... but yet she cannot pronounce the voiceless dental non-sibilant fricative /θ/ (thus "Eart")?!? Really? Oh wait, she's never been to Eart before... so
somehow she's come across this Latin word from another alien culture... and... uh... I mean... it's possible, but it's
IMMENSELY unlikely!
