Particles mark each role, so the noun chunks can be re-ordered; only the verb/adjective is fixed at the very end.
わたしは まいばん うちで テレビを みます。
I watch TV at home every evening.
まいばん わたしは うちで テレビを みます。
Every evening I watch TV at home. (re-ordered, same meaning)
A Japanese sentence is several “noun + particle” chunks followed by a predicate (verb or adjective). Because the particle (は, が, を, で, に…) shows each noun's job, the chunks may appear in different orders without changing the meaning.
What does NOT move: the verb or adjective stays at the end, and the topic は usually comes first. A common neutral order is topic → time → place → object → verb.
