Tilly is a cute name for a pet.

Tillie vallie, I can't believe it's already Friday!

Tilly-fally is just another way of saying tilly-vally.

Tilly-vally! I have no time for such nonsense.

I found a Tilly bone on the beach.

The geologist found a layer of tillite in the rock formation.

He is tilling the soil in the garden.

The tilling of the soil is an important step in farming.

Tillites are sedimentary rocks that are composed of unsorted and unstratified glacial debris.

The tillings in the field were carefully maintained.
