Diluted synonym
Diluted can mean made less concentrated or made weaker in effect. Suitable alternatives include less concentrated, watered down, weakened, or reduced in strength. Choose the replacement according to what was changed and how.
Meaning and context
For a liquid, diluted commonly describes reducing concentration by adding another substance, often a solvent. Less concentrated is a precise option when the concentration is the point. Watered down is natural in some contexts but can imply that water specifically was added.

Examples and usage
A diluted solution may be less concentrated. A diluted proposal may be a weakened version of an earlier plan. A watered-down speech suggests that some force or substance was lost. These examples use different senses and should not be exchanged mechanically.
What to check
A synonym should preserve the original claim. Softened may describe tone, whereas diluted can concern concentration or strength. In a technical instruction, retain the specified concentration and preparation method rather than replacing them with a loose adjective.
