abreast
UK: əˈbrɛst | US: əˈbrɛst
adv. side by side and facing the same direction
adv. keeping up to date with the latest information or developments
The word "abreast" originates from Middle English, combining the prefix "a-" (meaning "on" or "toward") with "breast" (referring to the chest or front of the body). The literal sense of being "side by side" (as if chests are aligned) evolved metaphorically to mean staying updated or aligned with progress. The imagery of physical alignment was extended to intellectual or informational alignment over time.
