There is no official dictionary definition for the exact phrase "hitches on." However, we can infer its meaning based on the individual meanings of the words "hitches" and "on."
The term "hitches" typically refers to a temporary stop or delay. It implies a snag, obstacle, or impediment that interrupts the smooth progression or execution of a particular activity or process. A hitch can occur due to unexpected problems, errors, or difficulties that need to be resolved before continuing.
Meanwhile, the preposition "on" can indicate continuation or attachment. It suggests that something is being added, joined, or connected to a particular situation, event, or process.
Considering these definitions, "hitches on" could refer to the act of encountering obstacles or delays that cause a disruption or pause to the ongoing activity or process, but subsequently finding a way to continue or progress despite these setbacks. It implies overcoming the initially encountered problems, making adjustments, and moving forward to complete the task or reach the desired outcome.
However, without a specific context, the exact meaning of "hitches on" may vary. It could also refer to hitching or attaching something to an existing situation, event, or process so as to enhance, modify, or influence it in some way. Again, the precise meaning would depend on the context in which the phrase is used.
