irresistible indecent wordformation curiosity

[Karel Oliva]

Just reacting quickly on Sergio's mail, and apologizing humbly in advance
for this slightly out of topic posting (concerns morphology and word
formation in general, not HPSG directly):
I wonder whether, having "conductors" and "semiconductors" on the one side,
English  has "isolation" and "penisolation" on the other side ? Would not
it be logical ?

:-)
