heretically

Synonym discussion
Sense: adverb/1
All four words describe departure from accepted norms, but they differ in connotation and domain. 'Dissidently' carries a political flavour — it implies active opposition to authority or established power structures, often in a collective or protest context. 'Iconoclastically' is more intense and specific: it suggests attacking or tearing down cherished institutions, traditions, or idols, not just disagreeing with them. 'Unorthodoxly' is the mildest and most neutral of the four — it simply means doing something in a non-traditional way, without the negative charge of 'heretically' or the aggressive tone of 'iconoclastically'. 'Radically' emphasises the degree of change (going to the root) rather than the oppositional stance. For example: a teacher who uses games in class teaches unorthodoxly; a journalist who exposes government corruption writes dissidently; an artist who mocks national symbols paints iconoclastically; an activist who demands complete systemic change thinks radically.
Etymology
Ultimately from Greek 'hairetikos' (able to choose, heretical), from 'hairein' (to choose). The word passed into Latin as 'haereticus', then into Old French as 'heretique', and entered English as 'heretic' in the 14th century. The adjective 'heretical' and the adverb 'heretically' were formed in English by adding '-ical' and '-ly' to 'heretic' during the 16th–17th centuries, a period when religious controversies made such vocabulary widely necessary.
