Ranked by relevance and common usage.
Keep "henceforward" when the sentence already sounds natural, when a synonym would add unintended emphasis, or when readers need the most familiar wording. A synonym should clarify or sharpen the message, not simply make the sentence look more varied.
If two options seem close, choose the one that best matches the audience and purpose of the sentence.
Choose a synonym only if it keeps the core idea of "henceforward" intact in the sentence you are editing.
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
Read the full sentence after the swap. Keep the synonym only when the sentence becomes clearer or more precise.
Review note: Synonym lists are ranked with lexical data and reviewed for practical writing value. Use the comparison notes, sentence evidence, and source labels together; a high-ranking synonym can still be wrong when the audience, register, or grammar changes.
After choosing a replacement for "henceforward", read the sentence once for meaning and once for rhythm. The best synonym should feel natural in the full sentence, not only accurate in a word list.
If the synonym makes the sentence slower, vaguer, or more dramatic than intended, keep "henceforward" or choose a simpler alternative from the closest-match group.
OpenGloss and ConceptNet supply richer edges like generalizations, collocations, and derivations.

"Whoe'er thou art, henceforward blot from mind / the Greeks, and leave thy miseries behind. / Ours shalt thou be; but mark, and tell me now, / what means this monster, for what use designed? / Some warlike engine? or religious vow? / Who planned the steed, and why? Come, quick, the truth avow."

“I wish you all,” he said, “my friends, to understand, however, that I have neither story to tell nor injuries to avenge. If a lady shall question me henceforward upon the incident of that unhappy night, I shall remain silent, and in future consider her as one who has shown herself desirous to break of her friendship with me; in a word, I will never speak to her again. But if a gentleman shall ask me the same question, I shall regard the incivility as equivalent to an invitation to meet him in the Duke's Walk, and I expect that he will rule himself accordingly.”
