The word "un-equivocalnesses" is a mouthful and may not be used often in daily conversations. However, if we were to look for synonyms that convey a similar meaning, we could consider words such as clarity, certainty, unambiguity, and explicitness. These words all emphasize the idea that something is clearly and unmistakably defined, leaving no room for doubt or confusion. Other related words that can be used include straightforwardness, definiteness, and precision. While long and complex words can often be useful in certain contexts, simpler and more accessible language can often be more effective when communicating ideas with clarity and impact.
