Ranked by relevance and common usage.
Keep "fouling" 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 "fouling" 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 "fouling", 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 "fouling" or choose a simpler alternative from the closest-match group.

A new type of fouling point indicator is being tried out by the London Transport Executive. Until now the standard method of indicating the point nearest to a junction of two stabling roads where a train can stand without fouling the adjacent road has been by fixing the letters "FP" [fouling point] to the sleepers of the road concerned.

Probably, rifling evolved from the early observation of the feathers on an arrow-and from the practical results of cutting channels in a musket, originally to reduce fouling, then because it was found to improve accuracy of the shot.
