The phrase "over-much" is an outdated expression meaning "excessively," "too much," or "more than necessary." It is commonly replaced by a variety of synonyms that convey the same idea more effectively, such as "excessively," "unnecessarily," "unreasonably," "unduly," "inordinately," and "overly." Other synonyms that can be used interchangeably with "over-much" include "superfluously," "extravagantly," "prodigiously," "immoderately," and "unwarrantably." These words help to convey exaggeration, hyperbole or overemphasis in a sentence, and can help to make writing more concise and clear. Writers should choose the most appropriate synonym for the context to avoid ambiguity and convey their intended message accurately.
