Resembling or related to ethene in structure or properties, especially describing compounds that have features similar to the ethene molecule.
From ethene + -oid (resembling, similar to). The suffix -oid creates adjectives meaning 'like' or 'resembling,' so ethenoid means 'ethene-like.'
The -oid suffix is a linguistic shortcut chemists use across the field—words like 'ketoid,' 'aldehydoid,' and 'ethenoid' all mean 'acting like or resembling' a specific functional group or parent compound.
