“The master-word is Work”
Osler makes sustained work the organizing principle of his address to medical students, emphasizing disciplined practice over brilliance without application.
Source note: The Master-Word in Medicine, address at the opening of the University of Toronto medical faculty buildings, October 1, 1903. This collection treats the line as historical professional rhetoric and not as an endorsement of excessive working hours.

“It is the open sesame to every portal”
The metaphor presents work as a means of opening opportunities that remain inaccessible to intention alone, within Osler’s larger argument for disciplined professional effort.
Source note: The Master-Word in Medicine, 1903. “It” refers to the master-word Work in the immediately preceding passage; the source page preserves that antecedent so the excerpt is not detached from its meaning.

“the paramount importance of the work-habit”
The address stresses that useful work becomes more dependable when it is habitual, making consistency part of professional formation rather than something left to occasional motivation.
Source note: The Master-Word in Medicine, 1903. Osler immediately acknowledges that acquiring the work-habit can be a hard battle; the context therefore supports persistence without turning the passage into a modern workaholism prescription.
