Pronunciation: [flˈɪmzɪnəs] (IPA) 
The word "flimsiness" is spelled with three syllables: /ˈflɪmzɪnəs/. The first syllable is pronounced like "flim" with a short "i" sound, followed by a "z" sound. The second syllable has a short "i" sound, and the third syllable is pronounced with a short "u" sound, like the word "bus". The spelling of "flimsiness" reflects its meaning, as this noun refers to the quality of being flimsy or easily broken or damaged.
Flimsiness refers to the quality or state of being weak, fragile, or insubstantial. It is a noun derived from the adjective "flimsy," and it pertains to objects, materials, or structures that lack strength, durability, or solidity. This term often suggests a tendency or susceptibility to easily break, tear, crumble, or collapse under pressure or strain.
In a literal sense, flimsiness characterizes physical objects that are thin, light, or poorly constructed, resulting in reduced stability or rigidity. For instance, a flimsy piece of paper may tear with minimal effort, a flimsy plastic bag might easily rip under a small load, or a flimsy door made of thin wood may be less secure and prone to damage. In a metaphoric sense, flimsiness can describe anything that lacks substance, credibility, or reliability. For example, an argument or reasoning can be deemed flimsy if it lacks solid evidence, logical coherence, or a strong foundation.
The term flimsiness can also be used to describe the overall poor quality, unsatisfactory design, or lack of robustness in products, structures, or ideas. It implies an inherent fragility, weakness, or lack of integrity that renders the concerned item or concept prone to failure or collapse. Flimsiness, therefore, suggests a notable deficiency in strength, stability, and overall reliability.
Thinness and weakness in texture; want of solidity.

The word flimsiness is derived from the adjective flimsy, which means easily torn, damaged, or weak. The etymology of flimsy traces back to the Middle English word flimysi, which originally referred to something of thin or slender build. It is believed to have originated from the Old Norse word flamsi, meaning thin or flat. Over time, the meaning of flimsy evolved to describe things that are lacking in strength, substance, or durability, leading to the noun form flimsiness.
