Definition of "umberella"

When days and years proclaim you’re old — A dottle, cripple, gouty fellow,Then for support you can lay hold O’ the upright of your umberella.

1893, David Herschell Edwards, One Hundred Modern Scottish Poets: With Biographical and Critical Notices, volume 15

Come, let's mix where Rockefellers walk with sticks / Or umberellas in their mitts / Puttin' on the ritz.

1946, Fred Astaire, Puttin' On the Ritz (song, based on 1927 version by Irving Berlin)
