Greek mythology? Now that I understand.
Genealogy? Poof! Your wish is my command.
What's this? Phonology? Something about the phone?
Ichthyology? Leave it alone.

Meteorology? (I like) Ideology? (Do tell).

Even the meat? You mean meteorology?
Frankly, I don't have the slightest ideology.
Fancy phraseology rings my bell.
Tricky, tricky, tricky, terminology, sounds so swell.

She drove off in her lexicology.

Then she drove her lexicology right into the oceanography,
so she had to hail a taxonomy to take her homeopathy.
