Logomachic refers to an argumentative or combative quality in language. If you want to express the same meaning using different words, there are a variety of synonyms that will do the trick. Some options include contentious, combative, quarrelsome, polemical, argumentative, disputatious, and belligerent. Each of these words suggests a confrontational or combat-oriented approach to language. Certain words may be more appropriate in certain contexts - for example, quarrelsome or belligerent may imply a more physical altercation. But in general, all of these words convey the same sense of a heated argument, often focused on semantics or language.
