Particle + の

The phrase 'Particle + の' is ambiguous because の generally functions as a nominalizer or possessive marker, but it can also appear in casual speech to connect phrases or emphasize a topic when combined with other particles. Different learners may encounter this in different contexts (e.g., nominalizing a clause that contains a particle, or forming noun phrases that involve の after a prior particle). If you intended a specific sub-point (for example, の used after verbs/adjectives to make a noun clause, or の in quotative/explanatory usage), please provide more detail.
