Pronunciation: [ʌnbˈa͡ʊndɪd] (IPA) 
The word "unbounded" (ʌnˈbaʊndɪd) is spelled with a "u" at the beginning, as opposed to "a" or "e," to indicate the long vowel sound in the first syllable. The "b" and "d" are both pronounced clearly with a brief pause between them, distinguishing it from similar words like "unfounded." The final syllable has an "-ed" ending, but the "d" is not pronounced as a separate sound. Instead, it creates a voiced ending for the "n" sound.
Unbounded is an adjective that describes something that has no limits, restrictions, or boundaries. It refers to a state or condition of being limitless or infinite. It implies the absence of any constraints, whether physical, mental, or conceptual.

The word unbounded comes from the combination of the prefix un- (which means not) and the adjective bounded. The adjective bounded refers to something that is limited, restricted, or confined within certain limits or boundaries. When the prefix un- is added, it negates or reverses the meaning of the word it is attached to. Therefore, unbounded means not limited, not restricted, or not confined within boundaries.
