In what cases do 平板 verbs change their pitch?

Question

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?

Answer 1

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.
