The suffix that combines the idea of a state or condition and is often used in linguistics is -ness. This suffix transforms adjectives into nouns, indicating a quality or state associated with the adjective it follows. For example, 'happy' becomes 'happiness,' capturing the state of being happy.

While -ment, -th, and -tude also form nouns, they are not specifically focused on the notion of state or condition in the same way that -ness does. -ment often conveys the result of an action (e.g., 'development'), -th can indicate a position or condition but is less widely recognized (e.g., 'depth'), and -tude generally refers to a state often associated with a quality or character (e.g., 'attitude'). Thus, -ness is the most specific and appropriate suffix to express the concept of a state or condition clearly within the context given.
