"He strutted briskly to secure the locomotive."

The → that (but "the" is an article, maybe synonyms are not needed here. Wait, the user says "every term," so maybe even articles. But articles don't have synonyms. Hmm. Maybe the user expects that, but it's tricky. Perhaps in the example they provided, they skipped articles and prepositions, but maybe not. Wait, in the example, "every each" replaced "every", but "term" became expression. So maybe articles and prepositions are skipped. The user should clarify, but since they provided an example where "every" was replaced, the user probably expects terms to be replaced when possible. If a word like "to" (preposition) doesn't have good synonyms, maybe just replace with similar words. "To" can be "toward" or "in order to". Hmm. Maybe the user expects that even prepositions are replaced. Okay.

"toward catching the train"

- She (pronoun) → He

- catch (verb) → secure

Original: "She walked quickly to catch the train."

But the original sentence is slightly different in structure. Let me adjust to maintain the same structure.
