IPA: /nɒnˈsɛljʊlə/
KK: /nɑnˈsɛljələr/
Not made up of cells; lacking cellular structure.
The virus is considered noncellular because it does not have a cellular structure like living organisms.
Noncellular → It is formed from "non-" (meaning not) and "cellular" (from Latin "cellula", meaning small room or chamber). The word "noncellular" means not having a cellular structure or not composed of cells.
Think of 'non-' meaning 'not' and 'cellular' referring to 'cells' — so noncellular describes something that does not consist of cells.
