1854, Samuel Butler, “Miscellaneous thoughts”, in The poetical works of Samuel Butler, page 244:
- For error and mistake, the less th' appear, / In th' end are found to be the dangerouser; / As no man minds those clocks that used to go / Apparently too over-fast or slow.
1928, Charles E. Mack, Two Black Crows in the A.E.F., page 55:
- "—and de letter say: 'It's getting dangerouser and dangerouser every minute over where de fighting is at.'"
2014, Criag Johnson, Any Other Name: A Longmire Mystery, page 11:
- “Oh jeez, if it isn't dangerous and dangerouser.” Sandy Sandburg, the sheriff of Campbell County, pulled out a chair, sat at our table, and propped up a large manila folder on the windowsill beside him, careful to pick a spot where the condensation wouldn't do any damage.
