IPA: /həˈlɒɡrəfɪkli/
KK: /həˈlɒɡrəfɪkli/
In a manner that relates to or uses holography, which is a technique for recording and reproducing three-dimensional images.
The data was stored holographically, allowing for a more efficient use of space.
Holographically → It is formed from "holograph" (from Greek "holos" meaning whole and "grapho" meaning to write) and the suffix "-ically" (meaning in a manner). The word describes something done in a manner that is whole or complete, often referring to three-dimensional representations created by holography.
Think of 'whole' ('holos') and 'writing' ('grapho') to remember that 'holographically' refers to something represented in a complete, three-dimensional way.
