The quality, condition, or characteristics of being a gymnosperm; the category or classification of plants that are gymnosperms.
From 'gymnosperm' plus '-ism,' a suffix creating abstract nouns for systems, practices, or states of being. This creates a noun describing the gymnosperm condition or grouping.
The '-ism' suffix is super productive in English—you can slap it on almost any noun to make an abstract concept! Here it turns a plant category into an idea.
