Some avoidance synonyms can be somewhat under-the-radar. For example, in the Wikipedia article on continuum mechanics, ‘assumption’ is used as an avoidance synonym for ‘hypothesis’ in the phrase ‘continuum assumption’, in order to avoid conflict with the notion of ‘continuum hypothesis’ in mathematics.
Here is the link to the Wikipedia article on continuum mechanics.
