Synonym selection checklist
- Match the part of speech before comparing meanings.
- Check whether the synonym changes intensity, formality, or emotional tone.
- Read the replacement inside the full sentence, not just beside "forthwith".
- Prefer the clearest word over the most unusual word when writing for speed or comprehension.
When not to replace "forthwith"
Keep "forthwith" 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.
Replacement workflow
1. Preserve meaning
Choose a synonym only if it keeps the core idea of "forthwith" intact in the sentence you are editing.
2. Tune tone
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
3. Re-read context
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.
Final fit check
After choosing a replacement for "forthwith", 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 "forthwith" or choose a simpler alternative from the closest-match group.

Awed by the vision and the voice divine / ('twas no mere dream; their very looks I knew, / I saw the fillets round their temples twine, / and clammy sweat did all my limbs bedew) / forthwith, upstarting, from the couch I flew, / and hands and voice together raised in prayer, / and wine unmixt upon the altars threw. / This done, to old Anchises I repair, / pleased with the rites fulfilled, and all the tale declare.
