What does fibrousness mean?
Fibrousness is the quality of being fibrous — that is, of being made up of or full of fibers. It describes a tangible, often tactile property: the stringy toughness of celery, the coarse chewiness of certain cuts of meat, the threadlike structure of plant stems, or the interwoven character of textiles and paper. The word functions as an abstract noun derived from the adjective 'fibrous', and it is used most often in technical and descriptive registers — botany, food science, nutrition, and materials engineering — where texture matters. Its connotations are largely neutral to mildly negative when applied to food, where excessive fibrousness suggests toughness and difficulty in chewing, but it can be positive in contexts such as dietary fiber or structural materials, where fibrous composition implies strength and resilience. Related terms like 'stringiness' and 'coarseness' capture overlapping shades of meaning.
nounThe quality or condition of being fibrous; the extent to which something is composed of or contains fibers, especially in texture.
- The physical texture or quality of containing or consisting of fibers, as in food, plant tissue, or other materials.
"The fibrousness of celery makes it satisfying to crunch but stubborn to chew."
"Cooking the stem too long only intensified its fibrousness."
"Textile graders assess the fibrousness of raw wool before spinning."
Rarely pluralized; the word is almost always used as an uncountable mass noun referring to a general quality.
"The report compared the fibrousnesses of various plant tissues."
That stringy pull when you bite into celery or mango? That's fibrousness — the same quality that makes flaky fish fall apart and rope hold fast.

Etymology of fibrousness
Fibrousness derives from the adjective 'fibrous', formed from the noun 'fiber' (Latin 'fibra', meaning a filament or thread) plus the adjectival suffix '-ous', with the abstract-noun suffix '-ness' added to denote a state or quality. The Latin root 'fibra' also underlies English words such as 'fibril', 'fibrosis', and 'fibroid'. The '-ness' suffix itself is a native Germanic element long used in English to form nouns of quality from adjectives.
How fibrousness is actually used
A somewhat formal or technical word, more likely to appear in scientific writing, food criticism, or materials descriptions than in everyday conversation, where speakers tend to say something is simply 'fibrous' or 'stringy'.
Easily confused with fibrousness
Fibrosity refers to the degree or density of fibers present, often as a measured property in materials science, while fibrousness is the general quality or texture of being fibrous.
