In what cases do 平板 verbs change their pitch?


I recently realized that 平板 verbs become 尾高 when there is a の after them. For
example:

戦うの→たたかうの{LHHHL}

寝るの→ねるの{LHL}

That really does happen right? Or am I mishearing? What are other situations
where 平板 verbs change their pitch like that?




Yes, that does happen. It happens in a couple other places, certainly
including ん but also:

  * から
  * けど
  * が (as a conjunction and (verb)がいい etc)
  * many sentences ending particles (ぞ (optional)、わ (male version only)、よ (optional)、さ、 な (negative imperative only)、っけ、 etc.)
  * に違いない
  * も (when it directly follows a verb — you can imagine it as an invisible の almost)
  * か (for compartmentalizer & for sentence-ending question marker in the rhetorical usage)
  * し
  * と (quotative particle)、って、なんて
  * と (conjunction particle, optional)

and probably more.
