Dear tsuwm...
I cannot believe that you don't like navicular!! I think that's the coolest word---and navy comes from it. 
Boat-shaped? That's a very useful word. Boat-shaped shoes, and boat-shaped pastry, boat-shaped noses, and boat-shaped bouquets--boat-shaped hotdog holders--boat-shaped trowels and boat-shaped windows...
Now throw in navicular--and you sound sophisticated!
Navicular bouquets thrown out navicular windows onto passersby with navicular noses casting navicular shadows over quickly padding feet in navicular boots...
I mean, the possibilities are endless! And stunning!
Best regards,
Wordwind [raspberry with navicular tongue]
