139th

The 139th is the ordinal designation used to identify the 139th item in a sequential series. It functions as a label that shows position rather than name, and its meaning depends entirely on the context in which it is used.

In military usage, many armed forces designate units, formations, and districts with numbers as part of their official titles. The 139th prefix thus identifies a specific unit within a long-standing sequence, though the exact type (regiment, battalion, wing, etc.) and national affiliation vary by country and service.

In government and politics, legislatures or assemblies may use ordinal numbers to label sessions, terms, or bodies. A "139th General Assembly" or equivalent would refer to a particular legislative session, with its own leadership, committees, and legislative record.

In geography and infrastructure, numbered streets, avenues, or districts often adopt ordinal designations to aid navigation within a grid system. A location described as the 139th Street or 139th Avenue is typically defined by its position relative to other numbered streets.

In culture, sports, and events, editions of ongoing competitions or annual observances may be numbered, with the 139th edition signaling its place in a long-running sequence.

Calendar usage notes that the 139th day of the year falls on May 19 in common years and May 18 in leap years.
