imitatant

Could you specify the intended sense or domain for "imitatant"? It is not a widely recognized English term, so it would help to know whether you want it defined as (a) a rare or historical English noun meaning “one who imitates,” (b) a term from another language (e.g., a French present participle related to imitation), (c) a concept in a fictional or speculative field, or (d) a different, specific usage. Once you provide the context, I can draft a concise wiki-style article under 300 words.
