It can be used when describing a mixture or blend that includes a vertical element, often in contexts like design, architecture, or data representation.
Example: "The artwork features a combination of a vertical line and a horizontal shape, creating a dynamic visual effect."
Alternatives: "a blend of a vertical" or "an amalgamation of a vertical".
Most languages of the world are taken to result from a combination of a vertical transmission process from older to younger generations of speakers or signers and (mostly) gradual changes that accumulate over time.

Our results demonstrate that the consistent prevalence of POWV observed in tick populations could be maintained by a combination of low vertical, intermediate cofeeding and high systemic transmission rates.
Prevalence increases due to a combination of perfect vertical transmission from mothers into their asexually derived offspring and efficient horizontal transmission enabling parasite spread [ 22, 27].
These clearly show that the movement during swing phase used to clear the foot from the substrate is a combination of both vertical and lateral deviation with the lateral component being appreciably larger than the vertical component.
