the five main logical particles (「が」, 「を」, 「に」, 「へ」, and 「で」) cannot be “combined” with one another
these particles specify the function of their noun and nouns cannot be more than one part of speech at a time
the two primary logical particles (「が」 and 「を」) do not combine with the non-logical particles
in any directly transitive sentence, both of these particles are there (even if not visible)
particle combinations do not create any new meaning, they just use the function of both particles at the same time
ex: 「０が冬には雪だるまを作る」 means “as for in-winter, (I) make snowman”
「には」 marks 「冬」 as when something is done, but also marks/contrasts it as the topic
ex: 「０が秋にも雪だるまを作る」 means “as for in-fall-also, (I) make snowman”
the nominalizing 「の」 particle can be used with any logical particle because it turns the thing before it into a noun (and nouns can be used with any logical particle)
ex: 「田中さんと一緒に泳ぐのが好きだ。」 means “The thing of going swimming with Tanaka-san is likable.”
