Etymology: This is the present participle and gerund of "sulphurise," a verb meaning to treat or combine with sulphur. The verb is simply the noun "sulphur" with the suffix "-ise" added. That suffix came through a long chain: from Ancient Greek "-izō," through Late Latin "-izō," into Old French as "-iser," and then into Middle English as "-isen." English later attached it to "sulphur" to form the verb.
