Gnomadic   a wandering, meandering gnome
Misgnomer a female gnome
Metrognome     uses the London Underground
Gnominate   lazy gnome, idle  
Gnomad  a sane gnome
Gnoman'sland    where male gnomes reside
Gnome de guerre     see agnominous
Agnominous  a gnome with nous
Gnome de plume not a real gnome, might be a plum!
Gnome de plump An overweight gnome
Gnome more   enough already!
